Heat Conduction In Gases and Liquids

The medium for the experiment is fed through a gap. The gap between the two elements was selected so that the transfer of heat due to convection can be ignored. It comprises a cylindrical heat exchanger with a heated inner cylinder made of aluminium and a water-cooled jacket. Due to the low temperatures and the polished surfaces, the radiation portion of the heat transfer is also negligible. This experimental unit enables experiments to be performed on steady-state thermal conduction in liquid and gaseous materials. Temperature sensors measure the temperature difference.
