Abstract In this paper, a NiTi SMA heat engine is proposed. It converts thermal energy from a source of temperature different to mechanical energy. The Assumed temperature difference is (70 oC). The temperature is obtainable when the engine is used in a geothermal source. But if the engine is used for ocean thermal energy, incorporated solar or heat pumped will be used. The engine behavior is simulated, and the model is compared to experimental data. The engine developed a maximum driving force of 17.3N, a torque of 0.9Nm, and an efficiency of 4.51%.
