National Institute of Technology Calicut

Heat Transfer Lab (UG)

Heat transfer is a phenomenon which takes place by virtue of temperature difference. Three different modes of heat transfer such as, Conduction, Convection and Radiation by which heat transfer occurs. Apparatus is available in the laboratory to conduct experiments and to understand these phenomena in comprehensive manner. Condensation is one more fascinating phenomenon occurs in nature where heat transfer is involved.

The various apparatus available in Heat Transfer Laboratory and their specifications can be found here.
