Abstract

The present study investigates the three-dimensional convective rotating hybrid nanofluid flow over a linear stretching/shrinking sheet under the influence of dissipative heat. The behaviour of nanofluids, which are mixtures of Ag and MoS \(_4\) nanoparticles in water in this study, is considered in the occurrence of convective flow and the impact of rotation. The linear stretching \(/\) shrinking sheet represents a common model in many industrial processes. The analysis also accounts for the effects of dissipative heat that arise due to viscous dissipation and Ohmic dissipation. A well-equipped set of transformations is used for the conversion of the non-dimensional form of the governing equations. Moreover, the adaptation of the Hamilton–Crosser conductivity model enhances the study due to enhanced physical properties. Further, the combined effect of nanofluid properties, convective flow, rotation and dissipative heat on the fluid flow and heat transportation features is examined followed by the numerical solutions adopted to find the solution of the transformed set of equations. The results obtained from this investigation will have potential implications for enhancing the use of nanofluid in industrial applications where efficient cooling of nuclear reactors, electronics cooling, automotive cooling systems, etc. are crucial. Further, use of nanofluid in optimising heat transfer processes in relevant engineering systems is vital.

摘要

本研究研究了在耗散热的影响下在线性拉伸/收缩片材上的三维对流旋转混合纳米流体流动。本研究中纳米流体是Ag和MoS_4纳米粒子在水中的混合物，其行为被考虑在对流的发生和旋转的影响中。线性拉伸\(/\)收缩片材代表了许多工业过程中的常见模型。该分析还考虑了由于粘性耗散和欧姆耗散而产生的耗散热的影响。一套完善的变换用于控制方程的无量纲形式的转换。此外，汉密尔顿-克罗瑟电导率模型的适应由于增强的物理特性而增强了研究。此外，还研究了纳米流体特性、对流流动、旋转和耗散热量对流体流动和热传输特性的综合影响，然后采用数值解来找到变换后的方程组的解。这项研究获得的结果将对加强纳米流体在工业应用中的使用产生潜在影响，在工业应用中，核反应堆、电子设备冷却、汽车冷却系统等的高效冷却至关重要。此外，使用纳米流体优化相关工程系统中的传热过程至关重要。
