This paper aims at developing non-similar solutions for heat transfer augmentation in ternary hybrid nanofluids. Nanofluid is composed of three distinct (Silver, Copper, Aluminum oxide) nanosize particles while water is considered as a base fluid. Darcy–Forchheimer expression with variable porosity and permeability is adopted. Joule heating and viscous dissipations are also considered. Non-similar approach is utilized. Numerical solutions are computed by bvp4c solver of MATLAB. Graphical illustrations for flow and thermal fields behavior are provided. Comparative results are obtained for ternary hybrid nanofluid and nanoliquid. Physical quantities such as skin drag coefficient and Nusselt number are computed and interpreted. Our results reveal that rate of heat transfer augments substantially for Ag/water nanofluid in comparison to other classes of nanofluid.

本文旨在开发三元混合纳米流体中增强传热的非相似解决方案。纳米流体由三种不同的（银、铜、氧化铝）纳米尺寸颗粒组成，而水被视为基础流体。采用具有可变孔隙度和渗透率的 Darcy-Forchheimer 表达式。还考虑了焦耳热和粘性耗散。采用非相似方法。数值解由 MATLAB 的 bvp4c 求解器计算。提供了流场和热场行为的图形说明。获得了三元杂化纳米流体和纳米液体的比较结果。计算并解释诸如皮肤阻力系数和努塞尔数之类的物理量。我们的结果表明，与其他类别的纳米流体相比，银/水纳米流体的传热速率显着增加。
