Abstract

The invention provides a multiphase thermoacoustic magnetohydrodynamic generator. The multiphase thermoacoustic magnetohydrodynamic generator comprises a plurality of thermo-acoustic magnetohydrodynamic power generation units, wherein the thermoacoustic magnetohydrodynamic power generation units are connected end to end through resonant tubes, each thermoacoustic magnetofluid power generation unit comprises a thermoacoustic engine and a magnetofluid power generator, and gas working media are arranged among the thermoacoustic engines, the magnetofluid power generators and the resonant tubes. According to the above mode, the thermoacoustic engine and the magnetohydrodynamic generator in each thermoacoustic magnetohydrodynamic power generation unit both adopt the gas working medium, so the problem of unstable gas-liquid interface of the existing thermoacoustic driving magnetohydrodynamic generator in space application can be avoided, the application of the thermoacoustic magnetohydrodynamic generator in a space microgravity environment is greatly expanded, and the working efficiency and the specific power of an existing thermoacoustic driving magnetohydrodynamic generator can be greatly improved by taking the gas resonance tubes as a resonance mechanism.

Description

technical field [0001] The invention relates to the technical field of thermoacoustic power generation, in particular to a multiphase thermoacoustic magnetic fluid generator. Background technique [0002] When an appropriate temperature gradient and sound field exist in a pipe, acoustic oscillations are spontaneously generated, converting thermal energy into mechanical energy in the form of acoustic waves, which is the thermoacoustic effect. As a new type of external combustion heat engine, the thermoacoustic engine uses the thermoacoustic effect to convert heat energy into sound energy, that is, mechanical energy in the form of sound waves. It has the advantages of reliable operation and long life without mechanical moving parts, high potential thermal efficiency and Environmentally friendly and other advantages. The sound energy generated by the thermoacoustic engine can be converted into electrical energy by coupling the thermoacoustic engine and the acoustic-electric co...
