And I remember standing there that day thinking about the disturbers of mine. 我还记得那天站在那边思虑着“粉碎我的协调的人”。
For the process of membrane separation without flow disturbers, the concentration polarization occurs mainly in a very narrow range near the membrane surface, and the degree of concentration polarization increases along the fluid flow direction but decreases with Reynolds number ( Re). 从无扰流器的膜分离过程来看,浓差极化主要集中在膜表面附近很窄的范围内,浓差极化程度沿流向逐渐增加,但随Re数增加而减小。
The laminar Blasius similarity solution was taken as the basic flow. One two-dimensional T-S wave and two symmetrical three-dimensional T-S waves were taken as the disturbers at the entrance. 流动的雷诺数选定为732,基本流为层流Blasius相似性解,计算域入口扰动形式为一个二维T-S波和一对对称的三维T-S波。
Different initial disturbers all caused transition, the amplitudes of two-dimensional waves were not the same until the breakdown, but the positions where mean flow was modified rapidly were the same, the processes that the modification of mean flow increased rapidly were almost the same. 不同初始扰动引起转捩,直至breakdown前,二维波的幅值都是不一样的,但平均流修正开始快速增长的位置是相同的,平均流修正快速增长的过程也是大致相同的。
