High Temperature Dependence of a Pulse Tube Engine

摘要

A pulse tube engine, which has no any moving part at high temperature, is a new type heat engine to generate power by using heat. It is a reverse of pulse tube refrigerator that already uses in space as a high-reliable sensor cooler. It is a potential new method to generate power or cooling power by using car waste heat. Its temperature dependence is investigated by a numerical simulation, which shows that its swept volume ratio of displacer over expand, and the phase angle difference between displacer and expander is almost no change with temperature change, which is very convenient for controlling the engine when high temperature is changed, which is common in the car.
