Effects of Heat Leakage and Internal Irreversibility on Quality Factor of Thermoacoustic System

Abstract:

The quality factor of the thermoacoustic system is calculated, considering the dissipations caused by viscous and thermal effects at the resonator walls, heat leakage and internal irreversibility. The quality factor was analyzed in several situations. And it was analyzed numerically with the stainless steel wire mesh as an example. It is found that the quality factor is increased monotonically with the resonant frequency, and decreased monotonically with heat leakage conductivity and irreversibility factor. The relationship between quality factor and the regenerator packing material was analyzed, it is found that quality factor is increased monotonically with porous materials characteristic factor. It is a certain theoretical significance for future research.
