The recent hypothetical analysis is to explore the effect of hall current and ion's slip for a peristaltic mechanism of non-Newtonian Rabinowitsch fluid model (lubricant blended with the viscosity index reformer) with the dynamic damping and stiffness features. The mathematical model is examined by considering the assumptions of low Reynold's number and long wavelength, the governing system of non-linear differential equations are solved with the help of the perturbation technique. The impact of numerous parameters associated with a fluid flow such as viscous damping, stiffness, rigidity, Hall parameter and Brickman number are intrigued for velocity profile, temperature distribution, and concentration profile. Results are strategized and deliberated for shear thickening, shear-thinning, and a viscous fluid model. It is observed that the momentum distribution is enhanced for larger values of stiffness, rigidity and viscous damping force parameters, but quite reverse nature is depicted for thermal distribution. The variations of streamline are presented graphically for the Hartman number and elastic parameters. Brinkman number is related to the viscous dissipation effects, so it contributes to enhancing the thermal distribution of fluid for all cases.

利用霍尔电流和离子滑移效应对顺应通道中的蠕动进行动态模拟

最近的假设分析是探讨霍尔电流和离子滑移对具有动态阻尼和刚度特征的非牛顿Rabinowitsch流体模型(润滑剂与粘度指数重整剂混合)的蠕变机理的影响。通过考虑低雷诺数和长波长的假设来检验数学模型,并借助摄动技术来求解非线性微分方程的控制系统。对于速度分布,温度分布和浓度分布,对与流体流相关的许多参数(例如粘性阻尼,刚度,刚度,霍尔参数和布里克曼数)的影响都充满了兴趣。为剪切增稠,剪切稀化和粘性流体模型对结果进行策略化和讨论。可以看出,对于较大的刚度,刚度和粘性阻尼力参数值,动量分布得到了增强,但是对于热分布却描述了完全相反的性质。针对Hartman数和弹性参数以图形方式显示了流线的变化。布林克曼数与粘性耗散效应有关,因此它有助于在所有情况下增强流体的热分布。
