Use of fin analysis for determination of thermal conductivity of material

The experiment demonstrates the use of fin analysis as one of the possible ways for determination of thermal conductivity of material by using fins. In the experiment the thermal conductivity of unknown material is determined by referring to the standard material of known thermal conductivity. In the experimental set-up, a suitably designed heater coil is used as a heat source. An Aluminium rod is used as reference material and the provision is made in the setup to attach a test rod of which thermal conductivity is to be determined. A Multipole Digital Temperature indicator with seven PT-100 thermocouples are used to measure the temperatures. The geometries of the test and reference rods are mandatory to be exactly same for analysis
