Abstract

This research work investigates the semi‐numerical analysis and heat transfer of MHD 2D, Copper Oxide, and Magnesium oxide engine oil base nanofluid with the consider effect of dynamic viscosity and convective boundary conditions (BCs). The convective BCs and the effect of dynamic viscosity on an extensible surface are considered by the flow system. We converted a set of PDEs into NODEs by applying the appropriate transformations. Using the HAM, we solve this dimensionless coupled equation one for temperature and other for velocity. The impact of various parameters for both temperature and velocity are demonstrated, such as the slip parameter, magnetic parameter (MP), Eckert number (EN), PN, and dynamic viscosity. In response to changes in developing factors, the flow features, such as temperature profiles (TPs) and velocity profiles (VPs), are analyzed and simulated using a physical description. The results of this study add to our knowledge of how engine oil‐based nanofluids promote heat transmission and offer practical advice for thermal management and engineering applications.
受动态粘度、磁场和对流边界条件影响的 CuO 和 MgO 发动机油基纳米流体的分析和热传递
本研究工作研究了考虑动态粘度和对流边界条件(BCs)影响的 MHD 2D 氧化铜和氧化镁发动机油基纳米流体的半数值分析和传热。流动系统考虑了对流边界条件和动态粘度对可扩展表面的影响。我们通过应用适当的变换将一组 PDE 转换为 NODE。利用 HAM,我们求解了这个无量纲耦合方程,一个是温度方程,另一个是速度方程。我们展示了各种参数对温度和速度的影响,如滑移参数、磁参数 (MP)、埃克特数 (EN)、PN 和动态粘度。针对开发因素的变化,使用物理描述分析和模拟了流动特征,如温度曲线(TP)和速度曲线(VP)。这项研究的结果增加了我们对发动机油基纳米流体如何促进热传递的了解,并为热管理和工程应用提供了实用建议。
