摘要
回热器内交变流动的研究是回热式制冷机研究的重点,采用数值模拟的方法对回热器内交变流动特性进行了研究。结果表明回热器内压力、速度分布不再呈波动状分布,而是近似的呈直线分布。回热器内的交变流动阻力系数是时间与位置的函数,也具有明显的波动性。
The oscillating flow in regenerators is one emphasis in the fields of refrigerator. The characteristics of the oscillating flow in the regenerator were investigated by number simulation. It result show that the pressure and the velocity distribution are not waves, but a line. The oscillating flow friction factor is a function of time and position. The oscillating flow friction factor also is a wave.
