Modeling and simulation of a thermomagnetic reciprocating engine by gravity.

Worldwide concern over global warming and the search for less harmful energy sources to the environment has driven the scientific community to develop means of sustainability. In this sense, we have developed a gravitational thermomagnetic engine, based on Tesla’s engine operating principle. A magnetic plate containing MnAs was used as working piece. An electric resistor was used as energy source to heat the plate. We present in this paper our mathematical model and calculations, which simulate the engine’s dynamics. Using an interactive software, we studied the heat transfer process on the plate using a one-dimensional finite element model associated with the thermomagnetic properties of the material. Some performance parameters were obtained and the engine applications are also discussed.
