摘要

本文研究了具有辐射效应的不可压缩流体的粘弹性纳米流体模型的完全发展的稳态流动。阐述了连续性、动量和能量方程,以理解流体流动的性质。利用相似变换,在射击技术的辅助下,用数值方法得到了产生的控制方程的解。此外,还利用图形分析了布朗运动参数、Weissenberg数、热泳态参数、渗透率参数、非牛顿参数和辐射参数对浓度、速度和温度场的影响。本文还讨论了Pr和γ对Nusselt数的影响以及nb和γ对Sherwood数的影响。

Numerical investigation of viscoelastic nanofluid flow with radiation effects
In this article, the fully developed steady state flow of an incompressible fluid pertained to as viscoelastic nanofluid model with radiation effects through a penetrable plate is studied. Continuity, momentum and energy equations are elaborated to comprehend the nature of the fluid flow. By using similarity transformations, the solution of arising governing equations is obtained numerically with the assistance of a shooting technique. Furthermore, the consequences of different parameters, that is, Brownian motion parameter, Weissenberg number, thermophoresis parameter, permeability parameter, non-Newtonian parameter and radiation parameter on concentration, velocity and temperature fields, are canvassed with the help of graphs. The effects of Pr and γ on Nusselt number and N b and γ on Sherwood number are also discussed with the assistance of graphs and tables for different values of dimensionless parameters.
