To investigate the roles of centrifugal instability on the linear growth rate of the flows, the azimuthal velocity of the basic flow is either centrifugally stable or unstable. 为了研究离心不稳定对线性增长率的影响,本研究中基本流的周向速度可以是离心稳定的,也可以是离心不稳定的。
The simulated and experimental results show that there exist a linear correlation between resistance and flow rate in DPF in the case of small flow rate, however, in the case of large flow rate, the relationship between them becomes a conic correlation. 试验和计算结果均表明,在较小流量时,壁流式过滤体的阻力与流量近似呈线性关系,在较大流量时,两者之间为二次曲线关系;
