Thermal conductivity of fluids with computer-controlled trainer (HT – 002) tends to illustrate basic experiments for targeted teaching on the topic of heat conduction in fluids. The trainer discusses the fundamental differences between thermal conductivity of gases and liquids.
- This trainer has been designed for investigation of the thermal conductivity of common fluids, e.g. Water, oil, air or carbon dioxide
- The trainer basically consists of two cylinders which are an electrically heated aluminum inner cylinder and a water-cooled copper outer cylinder.
- The electrically heated inner cylinder is suited in the water-cooled outer cylinder. There is a concentric annular gap between the two cylinders. This annular gap is filled with the fluid being studied.
- The heat conduction occurs from the inner cylinder, through the fluid to the outer cylinder.
- The narrow annular gap prevents the formation of a convective heat flux and allows a relatively large pass-through area while at the same time providing a homogeneous temperature distribution.
- The trainer is equipped with temperature sensors inside the aluminum cylinder and the outside of the annular gap.
- The trainer is equipped with a water source inlet and outlet for cooling to keep working on a steady state, and the experimented fluid inlet and outlet hoses.
- The trainer’s control panel permits heater ON/OFF, heater power control, heater power display, trainer ON/OFF and emergency stop.
- The unit is connected to a PC via USB to display the interactive software.
- The interactive software displays temperatures and power consumption, and permits generating the fitting curve of the experimented fluid and calculating the its thermal conductivity.
