驻波型热声制冷机板叠温度分布的研究

摘要

Based on the linear low amplitude sound field,the temperature distribution of the plate in the standing wave field is analyzed microscopically.The temperature of the board stack is simulated by the fluid software Fluent.It can be seen from the theory and simulation results that the standing-wave can form a temperature gradient and the infinite plate will be stacked on the high temperature and low temperature alternately appear temperature gradient.%基于驻波线性小振幅声场,从理论上分析了驻波声场板叠上温度分布,并用流体软件Fluent对板叠温度进行模拟仿真,由理论和仿真可知,驻波声场中板叠可以形成温度梯度而且无限长板叠上会形成高温低温交替出现的温度梯度.
