SR-WL373 Heat Conduction in Gases and Liquids Heat Transfer Trainer Vocational Training Equipment
Technical Description
Heat conduction in physics means the transfer of thermal energy between neighbouring atoms and molecules in a solid or in a fluid at rest.
The heat transport is substance-bound. The effect of pure heat conduction is hindered in fluids by convection effects. This can be prevented by enclosing the fluids in gaps.
The experimental unit serves to examine heat conduction properties of various fluids. The experimental unit is delivered together with a display and control unit.
The core element of the experimental unit is a cylindrical heat exchanger with a heated inner cylinder made of aluminium and a water-cooled jacket. There is a ring-shaped gap between the inner cylinder and the jacket, which is completely filled with the fluid to be examined. The width of the gap is such that the heat transfer by convection is negligible.
Due to the low temperature level and polished surfaces, radiation is also negligible.
The thermal conductivities k of various fluids such as water, oil, air, oxygen or carbon dioxide can be determined in experiments. Sensors record the temperatures and the consumed heating power at all relevant points.
The measured values can be read on digital displays.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
