Abstract

Salient features of hybrid nanofluid (MoS-SiO/water) for Darcy-Forchheimer-Brinkman porous space with variable characteristics is examined. Heat transfer analysis subject to viscous dissipation, nonlinear thermal radiation, and heat generation/absorption is carried out. Disturbance inflow is created by an exponentially stretching curved sheet. Relevant equations are simplified by employing boundary layer theory. Adequate transformations lead to a set of dimensionless equations. Velocity, temperature, and entropy generation rate are analyzed graphically. Comparative results are obtained for hybrid (MoS-SiO/water) and nanofluid (MoS-water and SiO-water). Physical quantities are analyzed through numerical data.

摘要

研究了具有可变特性的达西 - 福希海默 - 布林克曼多孔空间中混合纳米流体(MoS - SiO/水)的显著特征。进行了考虑粘性耗散、非线性热辐射以及热生成/吸收的传热分析。由指数拉伸的弯曲薄板产生扰动流入。通过应用边界层理论简化相关方程。适当的变换导致一组无量纲方程。对速度、温度和熵产生率进行了图形分析。获得了混合纳米流体(MoS - SiO/水)与纳米流体(MoS - 水和SiO - 水)的对比结果。通过数值数据对物理量进行了分析。
