The simulating result shows that there is little difference in the flow coefficient between the adjacent odd and even piston pumps, and the flow pulsation frequency is independent...
仿真结果表明，相邻值的奇偶数柱塞泵的流量脉动系数相差无几，且流量脉动频率与柱塞数的奇偶性无关。
In practice, choosing the static height of the bed layer and the frequency of the gas pulsation properly can increase the heat transfer coefficient.
在实际操作过程中，选择合理的床层静止高度和气流脉动频率对提高传热系数有利。
