In this work, a novel enhanced model of the thermophysical characteristics of hybrid nanofluid is introduced. An innovative kind of fluid called hybrid nanofluid has been engineered to increase the heat transfer rate of heat and performance of thermal system. A growing trend in scientific and industrial applications pushed researchers to establish mathematical models for non-Newtonian fluids. A parametric study on theheat transfer and fluid flow of a Williamson hybrid nanofluid based on AA7075-AA7072/Methanol overincessantly moving thin needle under the porosity, Lorentz force, and non-uniform heat rise/fallis performed. Due to similarity variables, the partial differential equations governing the studied configuration undergo appropriate transformation to be converted into ordinary differential equations. The rigorous built-in numerical solver in bvp4c MATLAB has been employed to determine the numerical solutions of the established non-linear ordinary differential equations. It is worthy to note that velocity declines for both AA7075/Methanol nanofluid and AA7075- AA7072/Methanol hybrid nanofluid, but highervelocitymagnitudes occur for theAA7075/Methanol whilethe Williamson fluid parameters increased. It is alsoconcluded that as the porosity parameter isincreased, the flow intensity decreases gradually. It is worthy to note that for both non-uniform heat-rise and fall parameters, the temperature of the fluid gets stronger. Mounting valuesof needle thickness parameter leads to reduction in fluid speed and temperature. It is noticedthat as volume fractions of both types of nanoparticles are augmented then fluidvelocity and temperature amplify rapidly. A Comparison of current and published results is performed to ensure the validity of the established numerical model.
在这项工作中,引入了一种新型的混合纳米流体热物理特性增强模型。一种名为混合纳米流体的创新型流体已被设计出来,以提高热传递速率和热系统性能。科学和工业应用中的一种发展趋势促使研究人员为非牛顿流体建立数学模型。对基于AA7075 - AA7072/甲醇的威廉姆森混合纳米流体在孔隙率、洛伦兹力和非均匀热升/降条件下,在不断移动的细针上的传热和流体流动进行了参数研究。由于相似变量,控制所研究构型的偏微分方程经过适当变换转化为常微分方程。采用MATLAB中bvp4c严格的内置数值求解器来确定所建立的非线性常微分方程的数值解。值得注意的是,对于AA7075/甲醇纳米流体和AA7075 - AA7072/甲醇混合纳米流体,速度均下降,但随着威廉姆森流体参数增加,AA7075/甲醇的速度幅值更高。还得出结论,随着孔隙率参数增加,流动强度逐渐降低。值得注意的是,对于非均匀热升和热降参数,流体温度都会升高。针厚度参数值的增加会导致流体速度和温度降低。可以注意到,随着两种类型纳米颗粒的体积分数增加,流体速度和温度会迅速增大。对当前结果与已发表结果进行了比较,以确保所建立数值模型的有效性。
