摘要

本研究介绍了倾斜磁流体力学(MHD)混合对流不可压缩流体与含有纳米流体和基础流体胶体组合的混合纳米颗粒的研究。在电流分析中使用Al2O3-Cu/H2O混合纳米流体来增强传热分析。辐射的影响也被置于能量方程中。主要的研究方法包括:首先将问题提供的方程转化为无量纲形式,然后以常微分方程的形式得到方程,然后利用动量方程和传递方程的解求解给定的常微分方程,得到方程的根。主要目的包括在适当的边界条件的帮助下对所得方程进行解析求解。结果可以用各种物理参数进行讨论,即拉伸/收缩瑞利数、拉伸/收缩参数、普朗特数等。此外,可以用适当的相似变换来检验皮肤摩擦和传热系数。本工作的主要意义是在分析方法的基础上解释混合对流流体的流动。最后的主要发现是,对于吸力和注入情况,拉伸/收缩瑞利数和质量蒸腾量的值越大,横向和切向速度越大。这是一种特殊的方法,它包括拉伸/收缩瑞利数,在分析中起着重要作用。本工作的目的是了解基于混合对流方法的解析解。

MHD Hybrid Nanofluid Flow over a Stretching/Shrinking Sheet with Skin Friction: Effects of Radiation and Mass Transpiration
The study of inclined magnetohydrodynamics (MHD) mixed convective incompressible flow of a fluid with hybrid nanoparticles containing a colloidal combination of nanofluids and base fluid is presented in the current research. Al2O3-Cu/H2O hybrid nanofluid is utilized in the current analysis to enhance the heat transfer analysis. The impact of radiation is also placed at energy equation. The main research methodology includes that the problem provided equations are first transformed into non-dimensional form, and then they are obtained in ordinary differential equations (ODEs) form. Then using the solutions of momentum and transfers equations to solve the given ODEs to get the root of the equation. The main purpose includes the resulting equations are then analytically resolved with the aid of suitable boundary conditions. The results can be discussed with various physical parameters viz., stretched/shrinked-Rayleigh number, stretching/shrinking parameter, Prandtl number, etc. Besides, skin friction and heat transfer coefficient can be examined with suitable similarity transformations. The main significance of the present work is to explain the mixed convective fluid flow on the basis of analytical method. Main findings at the end we found that the transverse and tangential velocities are more for more values of stretched/shrinked-Rayleigh number and mass transpiration for both suction and injection cases. This is the special method it includes stretched/shrinked-Rayleigh number, it contributes major role in this analysis. The purpose of finding the present work is to understand the analytical solution on the basis of mixed convective method.
