燃气驱动的热声发动机初步实验

Experiment of a thermoacoustic engine driven by LPG

在原有电驱动混合型热声发动机的基础上,设计建造了燃气驱动的混合型热声发动机,并进行了初步实验。以氮气为工质,在充气压力为1.2 MPa时发动机压比达到了1.29,在充气压力为2.4 MPa时得到了250.3 W的声功。通过采用弹性膜片阻断直流,在充气压力1.2 MPa时,系统最高压比达到1.34。

The experiment of a thermoacoustic engine driven by LPG, which is based on the original electricity reached 1 the filling MPa by u applicatio driven engine, was performed. Using nitrogen as working fluid, the maximum pressure ratio 1. 29 with the filling pressure of 1.2 MPa, and the maxin, um output power reached 250.3 W with pressure of 2.4 MPa. The maximum pressure ratio reached 1.34 with the filling pressure of 1.2 sing membrane to control the Gedeon steaming. The experiment result will be useful for the future n of thermoacoustic system driven by thermal energy.
