Heat Transfer & Thermal Science and Energy Laboratory

Heat Transfer laboratory provides fundamental and industrial knowledge about modes of heat transfer, like conduction, convection and radiation, and their application. Heat Transfer Lab consists of the following equipments:

Using the apparatus one can find the thermal conductivity of a given material and a composite structure which is one of the most important properties of a material in which heat transfer takes place by means of Conduction. Unsteady (Transient) state heat transfer is common in many of the thermal engineering applications where the temperature varies with time. Temperature as a function of time can be plotted using Transient conduction set up. Fins (extended surfaces) are commonly used to depict the heat transfer by conduction within solid and heat transfer by convection from the boundaries of the solid body. Pin-fin apparatus helps in calculating the rate of heat transfer dissipated to the surrounding air.

Heat transfer by convection mode can take place naturally, by means of buoyancy force called as natural convection or by forcing the fluid with the help of an external source like a blower/fan/pump, named as forced convection. The two apparatus available are to measure the convective heat transfer coefficient, heat transfer rate both by natural convection (for a pipe in vertical and horizontal position) as well as forced convection wherein the air is forced using a blower.

Heat exchanger is a device which is used extensively in almost all the engineering applications starting from electronic components (micro scale) to industrial power plants (macro scale), Parallel and counter flow heat exchangers are of one such type. Overall heat transfer coefficient, log mean temperature difference (LMTD) and the rate of heat transfer between the hot and cold fluid are the performance parameters that can be calculated using the apparatus.

Stefan Boltzmann’s constant and Emissivity are the two salient properties required in evaluating the heat transfer by radiation for a given substance and to compare the radiation emission between any given body and an ideal black body (Perfect emitter). These two properties can be obtained by means of the Stefan-Boltzmann’s Apparatus and Emissivity Apparatus.

Under Thermal Science and Energy Lab the following equipments are available:

First three comes under the classification of heat exchangers wherein each apparatus has its own advantages and limitations. Heat pipe (evacuated) experiment shows high thermal diffusivity when compared to copper and stainless steel pipes due to its design. It is the fastest removing heat exchanger out of existing systems. Shell and Tube and Cross flow heat exchangers are used to find the overall heat transfer rate and its effectiveness.

Fluidization is mostly used in catalytic cracking of petroleum and for better combustion of coal in power generation. They have high rates of heat transfer due to greater interfacial surface area of contact. The setup is used to find the heat transfer coefficient.

This lab can be utilized both at UG and PG level courses to meet their requirements as they give enough exposure while performing experiments which in turn helps in finding a research problem and going ahead with certain projects in the area of Thermal engineering, Energy and Heat Transfer.
