United Scientific Supplies Low Temperature Difference Stirling Engine
Illustrates conversion of heat energy into mechanical work using a thermodynamic cycle similar to the Carnot cycle.
Supplier: United Scientific Supplies LTDSE1
Description
- Runs by exploiting the heat flow generated by the small temperature differences between room temperature and a container of hot water or ice
- Transports heat from a warm surface to a cold one
- Larger temperature differences make the engine rotate faster
- Engine needs two pistons, a small power piston and a larger “displacement piston” that also stores heat energy
- Model runs at about 150rpm when powered by a cup of hot water
- Direction of rotation can be changed by switching the warm and cold surfaces
- Functions “in reverse” as a heat pump by putting in mechanical energy and creating a temperature difference
