在这篇研究论文中，我们研究了Darcy-Forchheimer三维微极性纳米流体流动的碳纳米管（CNTs）基于水。在旋转系统中的平行板和水平板之间的纳米流体流动进行检查。热辐射的影响被认为是在吸收/生成的目的，看到的浓度以及纳米流体和表面之间的温度变化而变化。渗透介质中的微极性纳米流体通过假设Darcy-Forchheimer模型来指定，其中浸透渗透空间服从Darcy-Forchheimer表达式。对于表面摩擦系数，它被认为是较大的弱浓度和较小的强浓度。本文主要研究了孔隙度、旋转和惯性系数分析的影响。为了研究速度和温度分布如何受到各种流动参数的影响，绘制了曲线图。首先将导方程转化为非线性微分方程组，然后用同伦方法求解。研究了流动的其他物理特性，如表面摩擦、热流和质量通量。本文主要研究了孔隙率、旋转系数和惯性系数等因素对颗粒运动的影响。(C)2018年作者。
In this research paper we examined Darcy-Forchheimer three-dimensional micro-polar nanofluid flow of carbon nanotubes (CNTs) based on water. The nanofluid flow is examined between parallel and horizontal plates in a rotating system. The thermal radiation impact is taken to be varying in the absorption/generation for the purpose, to see the concentration as well as the temperature modifications between the nanofluid and the surfaces. The micro-polar nanofluid in permeable media is designated by assuming the Darcy-Forchheimer model where drenching permeable space obeys the Darcy-Forchheimer expression. For Skin friction coefficient it is perceived to be larger for weak concentration and smaller for strong concentration. The impacts of the porosity, rotation and inertia coefficient analysis have been mainly focused in present investigation. Plots have been presented in order to study how the velocities and temperature profile get affected by various flow parameters. The leading equations are converted to a system of nonlinear differential equations and then homotopic method is employed for solution. The other physical features of flow such as Skin friction, heat flux and mass flux have been studied. The impacts of the porosity, rotation and inertia coefficient have been mainly focused in this research. (C) 2018 Author(s).
