中文摘要：
利用格子玻尔兹曼方法,直接对蚀刻薄片和层叠丝网回热器的微观结构流场进行了模拟。得到了两种回热器填料的微观流场和两端的压差。模拟结果显示,当回热器的直径、水力直径和填充率相近情况下,不同流速下蚀刻薄片卷裹式回热器的稳态阻力系数均比层叠丝网回热器小。稳态阻力系数的模拟变化趋势与实验一致。
英文摘要：
Based on Lattice Boltzmann Method （LBM） , the flow field in the microstructure of mesh screen and etched foil regenerators were simulated. The velocity and pressure drop were obtained by LBM. The simulation results show that velocity field in etched foil regenerator is better distributed than that of mesh screen. And the etched foil regenerator has less resistance coefficient than that of mesh screen regen- erator. The simulation results basically agree with the experiments.
