The main purpose of this article is to discuss the fluid flow flowing between two vertical rotating plates. The detailed analysis of fluid flow in the presence of nanoparticles by using the Koo–Kleinstreuer–Li (KKL) model with permeable surface is discussed. Initially, the fundamental laws for momentum and energy are developed and constructed in the form of Partial Differential Equations (PDEs). and calculate. Afterward these PDEs are reformed to ODEs by using similarity variables. The obtained system of equations is further solved by numerical method via shooting techniques and then solved with Runge-Kutta method. The obtained results from numerical solution for rotating vertical channel flow on a permeable surface are examined in form of velocity in x, y − direction and temperature profile for several parameters such as magnetic and rotation parameters, Reynolds number. It is important to note that by increasing the values of MHD parameter, velocity in transient direction decreases. With all the cases of suction and injection, mixed convection parameter depicts the increasing behaviour along a y − direction.

基于KKL相关性的可渗透表面旋转垂直通道中纳米流体流动和传热的热能性能

本文的主要目的是讨论在两个垂直旋转板之间流动的流体流动。讨论了使用具有可渗透表面的 Koo-Kleinstreuer-Li (KKL) 模型对纳米颗粒存在下流体流动的详细分析。最初,动量和能量的基本定律是以偏微分方程 (PDE) 的形式发展和构建的。并计算。之后这些偏微分方程通过使用相似性变量被转化为常微分方程。得到的方程组通过射击技术进一步用数值方法求解,然后用Runge-Kutta方法求解。以x , y方向速度的形式检验了从可渗透表面上旋转垂直通道流的数值解获得的结果 − 多个参数的方向和温度曲线,例如磁和旋转参数、雷诺数。需要注意的是,通过增加 MHD 参数的值,瞬态方向的速度会降低。对于吸入和注入的所有情况,混合对流参数描述了沿y  - 方向的增加行为。
