In this article we focused on the mixed convection flow of SWCNT-Water and MWCNT-Water over a stretchable permeable sheet. The nanofluid occupied porous medium. Darcy's law is used to characterize porous medium. The impact of viscous dissipation is considered. Transformation procedure is adopted to transform the governing PDE's system into dimensionless form. In order to solve the dimensionless PDE's system we used numerical method known as Finite difference method. Effects of flow variables i.e porosity parameter, suction parameter, Grashof number and Reynolds number on velocity, skin friction, temperature and Nusselt number are described graphically. The obtained results shows that velocity is dominant in SWCNT-Water over MWCNT-Water. Temperature is dominant in MWCNT-Water over SWCNT-Water.
在本文中，我们专注于可伸展渗透板上的 SWCNT-水和 MWCNT-水的混合对流流。纳米流体占据多孔介质。达西定律用于描述多孔介质。考虑了粘性耗散的影响。采用变换过程将控制 PDE 系统转换为无量纲形式。为了求解无量纲 PDE 系统，我们使用了有限差分法这一数值方法。流动变量（即孔隙率参数、抽吸参数、Grashof 数和 Reynolds 数）对速度、摩擦系数、温度和努塞尔数的影响以图形方式描述。得到的结果表明，SWCNT-水中的速度比 MWCNT-水中的速度更占主导地位。MWCNT-水中的温度比 SWCNT-水中的温度更占主导地位。
