摘要

本研究的主要目的是探讨杰弗里混合纳米流体在存在磁场、散热/热源、屈服应力和化学反应影响的情况下穿过移动多孔表面的流动情况。努塞尔特数由热辐射过程表征。局部方程受移动坐标的多孔体系控制,该体系描述了 Buongiorno 模型的流动情况。通过相似变换,得到的方程被转化为非线性常微分方程。受控方程由 RKF45 通过射击技术求解。重点是研究各种相关参数的物理特性,如壁面热通量、温度分布、流速和表面摩擦力。分析表明,较高的渗透率以及屈服应力、发热和磁场参数会增强温度分布并减缓热传递。随着化学反应和热源的增加,质量传输也随之增加。该模型可应用于热能工程过程中。

Yield Stress Impact on Magnetohydrodynamic Jeffery Hybrid Nanofluid Flow Over a Moving Porous Surface: Buongiorno’s Model
The main goal of the present study is to explore the flow of Jeffrey hybrid nanofluid crossing through a moving porous surface with the existance of magnetic field, heat sink/source, yield stress and chemical reaction impact. Nusselt number is characterized by the process of thermal radiation. The partial equations are governed during the moved coordinate’s porous regime that is depicting the flow for Buongiorno’s model. Employing similarity transformations, the obtained equations were turned into non-linear ordinary differential equations. The controlled equations were solved by RKF45 via shooting technique. The focus is in examining physical characteristics such as heat flux at the wall, temperature distribution, velocity of flow, and surface friction for a variety of related parameters. The analysis explained that higher permeability and parameters of yield stress, generation of heat and magnetic field enhance distribution of temperature and slow down the heat transfer. The mass transport is upsurged with increasing chemical reaction and heat source. The model is prepared as an application in processes of thermal engineering.
