摘要
通常情况下,抽吸/吹气用于控制通道的流体流动,这也是考虑这种值得注意的效应的原因。由于右侧板的摆动,考虑了沿 x 轴的流体速度。同时还考虑了加热右板对流动的热效应。由于旋转,流体和尘埃粒子具有复杂的速度,即一次速度和二次速度之和。为了将上述物理现象转换为数学形式,我们使用偏微分方程来模拟主题流态。采用了适当的非一维变量来对控制方程系统进行非一维化。在假定周期解的帮助下,偏微分方程系被简化为常微分方程系,然后利用 Poincare-Lighthill 扰动技术通过扰动解来求解。此外,还确定了工程利益量、努塞尔特数和皮肤摩擦。此外,还研究了各种参数对表皮摩擦、粘弹性流体和尘粒速度曲线的影响。值得一提的是,即使在共振情况下,吸力也会控制边界层意外增长。所获得的解决方案在注入情况下也是有效的。辐射参数、格拉肖夫数和二级参数的值增大时,会导致表皮摩擦力减小。另一方面,吸力、旋转、磁力、含尘流体和雷诺数会导致表皮摩擦力上升。
Couette flow of viscoelastic dusty fluid through a porous oscillating plate in a rotating frame along with heat transfer
Usually, suction/blowing is used to control the channel's fluid flow, which is why this worth-noting effect is considered. The fluid velocity is considered along the x-axis due to the oscillations of the right plate. The thermal effect on the flow due to the heated right plate is also considered. The fluid and dust particles have complex velocities due to the rotation, which are the sum of primary and secondary velocities. To convert the aforementioned physical phenomenon into mathematical form, partial differential equations are used for modeling the subject flow regime. Appropriate nondimensional variables are employed to nondimensionalize the system of governing equations. With the assistance of assumed periodic solutions, the system of partial differential equations is reduced to a system of ordinary differential equations which is then solved by the perturb solution utilizing Poincare–Lighthill perturbation techniques. The engineering interest quantities, the Nusselt number, and skin friction are also determined. The impact of various parameters on skin friction, viscoelastic fluid, and dust particle velocity profiles is also investigated. It is worth mentioning that suction controls the boundary layer to grow unexpectedly, even in the resonance case. The obtained solution is also valid in the case of injection. The radiation parameter, Grashof number, and second-grade parameter cause a decrease in skin friction as their values increase. On the other hand, the suction, rotation, magnetic, dusty fluid, and Reynolds numbers cause a rise in skin friction.
