根据气体密度、粘度和导热系数等物性参数随温度的变化规律 ,在对热声系统中热声转换的关键部件丝网板叠进行合理简化的基础上 ,给出了热声系统起振机理的一种初步解释 ,对进一步完善热声理论具有一定指导意义。
According to the variation law of the physical parameters such as gas density, viscosity and thermal conductivity with the temperature, on the basis of reasonable simplification of the key components of thermoacoustic conversion in the thermoacoustic system, the mechanism of the thermoacoustic system oscillation A preliminary explanation, to further improve the thermoacoustic theory has some guiding significance.
