Abstract

This research scrutinizes the radiative convective heat transfer of non-Newtonian ternary hybrid nanofluid across slant surface of equal quantities of nanoparticles dispersed in raw fluid subjected to a constant magnetic field. The contribution assumes the existence of an exothermic reaction a process of diffusion of nanoparticles of copper metal and metal oxides in the raw liquid to enhance combustion and particle concentration of reactants in chemical processes. The model is governed by thermal and mass relaxation times that appear in partial derivative equations and the mathematical analysis is derived using dimensionless quantities and subsequently solved using the RK45 technique. The computations indicate that both the exothermic reaction and the reaction rate factors increase heat distribution, facilitating the complete combustion process. Tri-nanofluid exerts the highest shear stress on the solid boundary while the minimal shear stress on the surface is seen in the case of mono-nanofluid. A 13.3% upgrade in the thermal efficiency is noticed if tri-nanoparticles are dispersed rather than mono-nanoparticles. Therefore, the significant rise in heat transmit is possible due to the dispersion of tri-nanoparticles.

质量和热弛豫时间以及放热化学过程对通过斜面的三元混合萨特比纳米流体流动的影响,以及活化能和线性对流限制
本研究仔细研究了在恒定磁场作用下,非牛顿三元混合纳米流体在原液中分散等量纳米粒子的斜面上的辐射对流传热。该研究假设存在放热反应,即金属铜和金属氧化物纳米粒子在原液中的扩散过程,以提高化学过程中反应物的燃烧和粒子浓度。该模型由偏导数方程中出现的热弛豫时间和质量弛豫时间控制,数学分析使用无量纲量推导,随后使用 RK45 技术求解。计算结果表明,放热反应和反应速率因子都会增加热量分布,从而促进整个燃烧过程。三纳米流体对固体边界产生的剪应力最大,而单纳米流体对表面产生的剪应力最小。如果分散三纳米颗粒而不是单纳米颗粒,热效率会提高 13.3%。因此,由于三纳米粒子的分散,热传导率有可能大幅提高。
