Abstract
It is useful to recover various waste heat in power plants. So we have proposed a heat engine using shape memory alloy wires which work at cyclic supplying hot/cold water. The purpose of this study is to measure the output of the engine under various conditions (cyclic rate, cooling temperature, load torque) and to clarify the best working conditions of the newly developed heat engine. As a result, output power increases with an increase of cyclic rate in the limited test conditions. Total work obtained during working life of SMA of the heat engine becomes maximum when output power becomes maximum.
