Abstract The mathematical modeling of hybrid nanofluid flow and heat transfer with entropy generation toward parabolic trough surface collector (PTSC) inside the solar-powered ship (SPS) is performed. The mathematical model used non-Newtonian Oldroyd-B model amidst a constant inclined magnetic field influence is being considered. The mathematical model is then reduced by adopting appropriate similarity transformation into a higher-order nonlinear differential equations system. The reduced model is computed using the well-known technique called the Keller Box scheme. Physical parameters effectiveness, for instance, thermal radiation, viscous dissipation, hybrid nanoparticles, and Joule heating, is displayed in graphs. The silver-ethylene glycol (Ag-EG) characteristic performance outperformed the silver-magnetite-ethylene glycol (Ag-Fe3O4/EG). The maximum efficiency of Ag-EG is about 26.3%, while the minimum is at least 5.6%.

在抛物槽太阳能集热器中使用 Oldroyd 混合纳米流体对太阳能船的热分析表征：一种最佳热应用

摘要 对太阳能动力船 (SPS) 内的抛物槽表面集热器 (PTSC) 进行熵产生的混合纳米流体流动和热传递的数学建模。正在考虑在恒定倾斜磁场影响中使用非牛顿Oldroyd-B模型的数学模型。然后通过采用适当的相似变换将数学模型简化为高阶非线性微分方程系统。使用称为 Keller Box 方案的众所周知的技术计算简化模型。物理参数的有效性，例如热辐射、粘性耗散、混合纳米粒子和焦耳热，以图表形式显示。银-乙二醇 (Ag-EG) 的特性性能优于银-磁铁矿-乙二醇 (Ag-Fe3O4/EG)。Ag-EG 的最大效率约为 26.3%，而最小值至少为 5.6%。
