K. N. Asha and Dr. Neetu Srivastava, “Magnetic repercussion on the different shaped copper nanoparticles to improve vasodilatation effect in stenosed artery.”, Materials Today:, vol. 44, Part 1, 2021, Pages 2142-2146. 2021.[Abstract]

In the present article, we have analysed the impact of different shapes of nanoparticles on the flow significant parameters in the blocked arteries in the presence of magnetic effect. To explore the impact of nanoparticles of different shapes in the blocked artery, a wide range of nano-fluid volume fractions, Hartmann numbers and nanoparticle shape factors is used. To analyse the vasodilatation effect and temperature, the local Nusselt number and wall shear stress are evaluated analytically as well as graphically. It is graphically shown that the laminar nanoparticles have shown better results for all significant flow quantities.

A. U. Nair and Dr. Neetu Srivastava, “Analysis of Eigen Frequency Through a Simple Architectural Acoustic Modal.”, Journal of Physics: Conference Series, vol. 1172, 2019.[Abstract]

In this paper, we have displayed an answer for the portrayal of the room acoustics field with the mix of uniform impedance limit conditions forced on a few dividers utilizing Fourier strategy. Acoustic limit conditions are communicated in the terms of retention coefficient esteems. In this issue, the Fourier technique is determined zas the blend of three one-dimensional Sturm-Liouville (S-L) issues with Robin-Robin limit conditions at the first and second measurement and Robin-Neumann ones at the third measurement. The Fourier strategy requires an assessment of eigenvalues and eigenfunctions of the Helmholtz condition, by means of the arrangement of the eigenvalue condition, every which way. The arrangements are examined utilizing chart. As a curiosity, it is exhibited that the Fourier technique gives a helpful and productive approach for a room acoustics with various estimations of divider impedances. Hypothetical contemplations are shown for rectangular cross-area of the live with specific proportion. Results got in the paper will be a perspective to the numerical figuring's. © Published under licence by IOP Publishing Ltd.

Dr. Neetu Srivastava, “Rayleigh type streaming effect on magnetohydrodynamic characteristics of fluidized bed particles”, Powder Technology, vol. 320, pp. 108-113, 2017.[Abstract]

We developed and implemented a theory, involving the propagation of a wave in a magnetic field for boundary layer analysis of flow structures. Our investigation revealed that the position of nodes in a standing wave is a function of the applied magnetic field. Hence, an approximate solution to the acoustical wave problem near a rigid wall was derived using the perturbation theory. Our results revealed that the velocity of the steady flow outside the boundary layer was independent of viscosity but was dependents on magnetic field. The practical implication of the derived result has been presented by discussing one illustration: a case in which an external standing wave is imposed in the transverse direction with respect to the main flow. The flow may be described using the three non-dimensional parameters. Streamline behavior was plotted for the volumetric flow rate analysis of the problem. © 2017 Elsevier B.V.

Dr. Neetu Srivastava, “MHD flow between two non-coaxial disks rotating at different speeds”, Rendiconti del Circolo Matematico di Palermo Series 2, pp. 1–12, 2017.[Abstract]

Flow characteristics of an electrically conducting viscous incompressible fluid, due to an infinite impervious eccentrically rotating disk with a slight difference in speed, has been investigated in the presence of uniform magnetic field which is applied in the direction normal to the flow. Flow governing equation between the eccentrically placed disks is solved by the perturbation method. Analytical expressions for the velocities, moment at the disk and shearing stress were derived and the effects of various parameters upon them are examined. More »»

Dr. Neetu Srivastava, “Hydromagnetic forced flow of a viscous fluid through a heterogeneous porous medium induced by an impervious rotating disk”, International Journal of Dynamical Systems and Differential Equations, vol. 5, pp. 288-301, 2015.[Abstract]

This research is concerned with the forced flow of an electrically conducting viscous incompressible fluid in heterogeneous porous medium due to the rotation of disk. Whole analysis is carried out in the presence of normal magnetic field. It is assumed that the flow in the porous medium is governed by the Brinkman equation. Invoking suitable transformations, the flow governing partial differential equations are non-dimensionalised and are solved using the perturbation method. At the interface (porous-porous medium), a modified set of matching condition suggested by Ochoa-Tapia and Whitaker is applied. Analytical expressions for the velocities, moment at the disk and shearing stress are computed and the effects of various parameters upon them are examined. © 2015 Inderscience Enterprises Ltd.

Dr. Neetu Srivastava, “Analysis of flow characteristics of the blood flowing through an inclined tapered porous artery with mild stenosis under the influence of an inclined magnetic field”, Journal of Biophysics, 2014.[Abstract]

Analytical investigation of MHD blood flow in a porous inclined stenotic artery under the influence of the inclined magnetic field has been done. Blood is considered as an electrically conducting Newtonian fluid. The physics of the problem is described by the usual MHD equations along with appropriate boundary conditions. The flow governing equations are finally transformed to nonhomogeneous second-order ordinary differential equations. This model is consistent with the principles of magnetohydrodynamics. Analytical expressions for the velocity profile, volumetric flow rate, wall shear stress, and pressure gradient have been derived. Blood flow characteristics are computed for a specific set of values of the different parameters involved in the model analysis and are presented graphically. Some of the obtained results show that the flow patterns in converging region (<0), diverging region (>0), and nontapered region (=0) are effectively influenced by the presence of magnetic field and change in inclination of artery as well as magnetic field. There is also a significant effect of permeability on the wall shear stress as well as volumetric flow rate. © 2014 Neetu Srivastava.

Dr. Neetu Srivastava, “MHD Flow of the Micropolar Fluid between Eccentrically Rotating Disks”, International Scholarly Research Notices, vol. 2014, 2014.[Abstract]

This analytical investigation examines the magnetohydrodynamic flow problem of an incompressible micropolar fluid between the two eccentrically placed disks. Employing suitable transformations, the flow governing partial differential equations is reduced to ordinary differential equations. An exact solution representing the different flow characteristic of micropolar fluid has been derived by solving the ordinary differential equations. Analysis of the flow characteristics of the micropolar fluid has been done graphically by varying the Reynolds number and the Hartmann number. This analysis has been carried out for the weak and strong interactions. More »»

This paper deals with the analytical investigation of Casson model for axisymmetric pulsatile blood flow through an inclined stenosed artery of a periodically accelerated body under the influence of a magnetic field. Invoking suitable transformations, the flow governing partial differential equations are non-dimensionalised. For these non-dimensionalised equations, an exact solution representing the different flow characteristic has been derived by employing the perturbation method. Plug flow radius, plug flow velocity, flow rate and impedance analysis of the Casson fluid have been done graphically by varying the yield stress, inclination of artery, body acceleration and pressure gradient. Some important results are obtained pertaining to the medical interest. © 2014 Inderscience Enterprises Ltd. More »»

A. C. Srivastava and Dr. Neetu Srivastava, “Flow of a viscous fluid at small Reynolds number past a porous sphere with a solid core”, Acta Mechanica, vol. 186, pp. 161–172, 2006.[Abstract]

Uniform flow of an incompressible viscous fluid at small Reynolds number past a porous sphere of radius a with a solid concentric spherical core of radius b has been discussed. The region of the porous shell is called zone I which is fully saturated with the viscous fluid, and the flow in this zone is governed by the Brinkman equation. The space outside the shell where clear fluid flows is divided into two zones (II and III). In these zones the flow is discussed following Proudman and Pearson's method of expanding Stokes' stream function in powers of Reynolds number and then matching Stokes' solution with Oseen's solution. The stream function of zone II is matched with that of zone I at the surface of the shell by the condition suggested by Ochoa – Tapia and Whitaker. It is found that the drag on the spherical shell increases with the increase of the $łambda$ (=b/a) and also with the increase of the Darcy number. The graph of dimensionless drag against $łambda$ for various values of Reynolds number shows that the drag increases with the increase of the Reynolds number for all values of $łambda$.

A. C. Srivastava and Dr. Neetu Srivastava, “Flow past a porous sphere at small Reynolds number”, Zeitschrift für angewandte Mathematik und Physik ZAMP, vol. 56, pp. 821–835, 2005.[Abstract]

low of an incompressible viscous fluid past a porous sphere has been discussed. The flow has been divided in three regions. The Region-I is the region inside the porous sphere in which the flow is governed by Brinkman equation with the effective viscosity different from that of the clear fluid. In Regions II and III clear fluid flows and Stokes and Oseen solutions are respectively valid. In all the three regions Stokes stream function is expressed in powers of Reynolds number. Stream function of Region II is matched with that of Region I at the surface of the sphere by the conditions suggested by Ochao-Tapia and Whitaker and it is matched with that of Oseen's solutions far away from the sphere. It is found that the drag on the sphere reduces significantly when it is porous and it decreases with the increase of permeability of the medium.
