R. Rajesh and G., D. Rakesh S., “Effect on the drag coefficient of various spiked cylinders during buzz phenomenon subjected to hypersonic flows”, Brazilian Society of Mechanical Sciences and Engineering, vol. 42, no. 6, 2020.[Abstract]


Pulsation mode of transient flow behavior may occur in a violent manner in case of spiked cylinders depending on the geometry, type of spikes, and free stream conditions. Drastic pressure fluctuations near the face of the afterbody have been observed in most cases of pulsating flow mode and thus resulting in drastic variations in the coefficient of drag of the spiked body. The transient analysis of variations in Cd with spike length for various spiked cylinders have been carried out in the current work. The variations in Cd during one complete cycle as well as variations in time-averaged value of Cd with increase in L/D ratios have been analyzed. These variations have been explained with respect to the localized pressure fluctuations, shift in foreshock–aftershock interaction region, effect of effective shielding, and increasing spike lengths. It was found that aerodisk spiked cylinder had the least time-averaged Cd. The Cd for various other spiked bodies has also been summarized over a range of feasible spike lengths and an optimum design of the spiked body in terms of the spike shape and L/D has also been suggested.

The presentation in this paper briefs the experimental results obtained for evaluating the hardness and comparing with its microstructural pattern. Mild steel chills (MSC) are used to check the chilling effect. The results show that chill position influences the hardness of cast iron. Increase in hardness is observed by placing MSC at different locations. Specimens were prepared for microstructural examination using scanning electron microscope (SEM). Microstructure analysis was also carried out to evaluate the graphite morphology and carbide content using material plus and imageJ analyzer. Longer graphite flakes fare found in normally manufactured grey cast iron (GCI) without using MSC. Low size graphite’s and formation of carbides in the form of needles are seen near the chilled end surface. Effect of MSC position on hardness is studied and analyzed using image analyzers.

Transient numerical analysis has been carried out by simulating the fluid flow over sharp, conical, blunt, hemispherical, and aerodisk spiked cylinders. They have been subjected to hypersonic flow of Mach number 6.1, at zero angle of attack, so as to investigate the variations of frequency and thus the Strouhal number during hypersonic buzz phenomenon at various L/D ratios by capturing the flow unsteadiness using Ansys Fluent solver. It has been concluded that the frequency of hypersonic buzz is maximum at a particular L/D ratio known as the critical L/D ratio, which is unique for each type of spike. Above the critical L/D ratio, the buzz frequency decreases almost linearly with an increase in the L/D ratio, and below the critical L/D ratio, the frequency decreases drastically with a reduction in L/D, and finally the hypersonic buzz ceases to occur below a certain L/D ratio for every type of spiked body. Analysis of the aerodisk spiked cylinder revealed no hypersonic buzz phenomenon for any practical L/D ratios. Further, the correspondence between CD and pressure history at the probe point has also been verified.

Accelerometer based force balance system is a common technique used in shock tunnels to measure aerodynamic forces over models. This internally mountable force balance has rubber bushes, which facilitate an unrestrained movement of the model during the short test times of the tunnel. In some particular model-balance systems, when there are high energy flows, we may find the rubber bushes used in those balance systems shearing out. However, the behaviour of these rubber bushes on the predetermined acceleration history is not much familiar. To find out the effect of rubber bushes, a numerical approach is explored. An unsteady analysis of the flow through the shock tunnel and a blunt body has been carried out first. Finite element analysis is then executed to predict the acceleration and this value is analysed with that of the experimental value of acceleration. The prediction of acceleration values for different blunt bodies can be made with these results with different flow conditions and also for different angles of attack. © 2017 Pushpa Publishing House, Allahabad, India.

The deformation dynamics of metal foils (&lt;0.25 mm thick) subjected to micro-blast wave are presented in this paper. The energy of micro-blast wave emanating from the open end of a polymer tube is used to deliver micro-particles for bio-medical applications. In these experiments metal foils are used to transfer the energy of the micro-blast wave to the micro-particles. Using cubic root scaling law the over pressure of the blast wave at the open end of the polymer tube is estimated and using this peak plate over pressure is estimated. The finite element analysis is used to estimate the velocity profile of the deforming metal foils. The finite element analysis results are compared with experimental results for the maximum deformation and deformed shape. Based on the deformation velocity, metal foil to be used for experiments is selected. Among the materials investigated 0.1 mm thick brass foil has the maximum velocity of 205 m/s and is used in the experiments. It is found from finite element analysis that the particles deposited within a radius of 0.5 mm will leave the foil with nearly equal velocity (error &lt;5%). The spray cone angle which is the angle of deviation of the path of particles from the axis of the polymer tube is also estimated and found to be less than 7° up to a radius of 0.75 mm. Illustrative experiments are carried out to deliver micro particles (0.7 μm diameter tungsten) into plant tissues. Particle penetration depth up to 460 μm was achieved in ground tissue of potato tuber. © 2012 Elsevier Ltd. All rights reserved.</p>

<p>Small quantity of energetic material coated on the inner wall of a polymer tube is proposed as a new method to generate micro-shock waves in the laboratory. These micro-shock waves have been harnessed to develop a novel method of delivering dry particle and liquid jet into the target. We have generated micro-shock waves with the help of reactive explosive compound [high melting explosive (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) and traces of aluminium] coated polymer tube, utilising ∼9 J of energy. The detonation process is initiated electrically from one end of the tube, while the micro-shock wave followed by the products of detonation escape from the open end of the polymer tube. The energy available at the open end of the polymer tube is used to accelerate tungsten micro-particles coated on the other side of the diaphragm or force a liquid jet out of a small cavity filled with the liquid. The micro-particles deposited on a thin metal diaphragm (typically 100-μm thick) were accelerated to high velocity using micro-shock waves to penetrate the target. Tungsten particles of 0.7 μm diameter have been successfully delivered into agarose gel targets of various strengths (0.6-1.0 %). The device has been tested by delivering micro-particles into potato tuber and Arachis hypogaea Linnaeus (ground nut) stem tissue. Along similar lines, liquid jets of diameter ∼200-250 μm (methy-lene blue, water and oils) have been successfully delivered into agarose gel targets of various strengths. Successful vaccination against murine salmonellosis was demonstrated as a biological application of this device. The penetration depths achieved in the experimental targets are very encouraging to develop a future device for biological and biomed-ical applications. © Springer-Verlag 2012.</p>

Shock waves are one of the most efficient mechanisms of energy dissipation observed in nature. In this study, utilizing the instantaneous mechanical impulse generated behind a micro-shock wave during a controlled explosion, a novel nonintrusive needleless vaccine delivery system has been developed. It is well-known that antigens in the epidermis are efficiently presented by resident Langerhans cells, eliciting the requisite immune response, making them a good target for vaccine delivery. Unfortunately, needle-free devices for epidermal delivery have inherent problems from the perspective of the safety and comfort of the patient. The penetration depth of less than 100 μm in the skin can elicit higher immune response without any pain. Here we show the efficient utilization of our needleless device (that uses micro-shock waves) for vaccination. The production of liquid jet was confirmed by high-speed microscopy, and the penetration in acrylamide gel and mouse skin was observed by confocal microscopy. Salmonella enterica serovar Typhimurium vaccine strain pmrG-HM-D (DV-STM-07) was delivered using our device in the murine salmonellosis model, and the effectiveness of the delivery system for vaccination was compared with other routes of vaccination. Vaccination using our device elicits better protection and an IgG response even at a lower vaccine dose (10-fold less) compared to other routes of vaccination. We anticipate that our novel method can be utilized for effective, cheap, and safe vaccination in the near future

Alumina nanoparticles were synthesized using aluminium nitrate and lemon extract, lemon being an eco-friendly and non-toxic material. The synthesis was carried out using salt solution and the above extract in 1:1 ratio, radiated with the microwaves at 600W for 5 minutes. The synthesis was carried with and without the stabilizing agent to know the role played by it. The stabilizing agent used was sodium citrate which is environmental friendly. The amount of stabilizing agent used was varied and the optimum amount for better stability was found out. The nanoparticles thus formed were characterized by using UV Visible (UVVis) Spectroscopy, Dynamic Light Scattering and Zeta Analyzer. The nano particles had an average size of 460nm. This method of synthesis has proven to be faster than any other method because of the involvement of microwave heating. Above all, the synthesized nano particles may have anti-bacterial and anti-fungal properties which have a scope for future study.

The objects moving at high speeds encounter forces which tend to decelerate the objects. This resistance in the medium is termed as drag which is one of the major concerns while designing high speed aircrafts. Another key factor which influences the design is the heat transfer. The main challenge faced by aerospace industries is to design the shape of the flying object that travels at high speeds with optimum values of heat generation and drag. This study deals with computational analysis of sharp and blunt cones with varying cone angles and nose radii. The effect of nose radius on the drag is studied at supersonic and hypersonic flows and at various angles of attack. It is observed that as the nose radius is increased, the heat transfer reduces &amp; the drag increases and vice-versa. Looking at the results, the optimum value of nose radius can be chosen depending on the need of the problem

The popularity of LED panel as a source of illumination has soared recently due to its high efficiency. However, the removal of heat that is produced in the chip is still a major challenge in its design since this has an adverse effect on its reliability. If high junction temperature develops, the colour of the emitted light may diminish over prolonged usage or even a colour shift may occur. In this paper, a solution has been developed to address this problem by using a combination of heat pipe and heat fin technology. A single-phase and a two-phase heat pipes have been designed theoretically and computational simulations carried out using ANSYS FLUENT. The results of the theoretical calculations and those obtained from the simulations are found to be in agreement with each other.

Three fluid heat exchangers involving twothermal communications as well as three thermal communications have been investigated for the effect of change in the intermediate fluid temperature on the effectiveness of the heat exchangers, using both theoretical and simulation studies. The objective of these heat exchangers is identified as cooling of hot fluid. The simulations are repeated for hot fluids with different specific heats. The effect of change in the conducting material on the effectiveness in a three thermal communications heat exchanger has been investigated. The pressure drop calculations are also done for the heat exchangers.
