Abstract

The main concern of this work is to analyze performance of hybrid nanoparticles in improving thermal behavior on Williamson fluid through the heated cylinder on convective heating. Graphene and magnetic oxide were diffused by the Williamson liquid concurrently. This model for efficient thermal properties by the hybrid nano-fluids (the mixture of graphene, Williamson fluid, and magnetic oxide) was applied to model this transfer of heat and its outcomes by the set of complex numerical expressions about momentum and energy conservation. The equations were determined mathematically by bvp4c function in MATLAB. This parametric analysis was imposed, and the important enhancement was by thermal behavior of Williamson fluid when the hybrid nanoparticles (magnetic oxide and graphene) were noted. This wall heat flux by hybrid nano-Williamson fluid (magnetic oxide, the combination of graphene and Williamson fluid) was essentially established higher than that of thermal behavior on the mixture by graphene and the Williamson fluid. This wall shear stress increases when the fluid parameter and magnetic field are raised. This rate of heat transmission raises this thermal radiation, and Biot numbers were raised. These hybrid nanofluids had several practical functions in the new industry like that in nanodrug delivery system, micro-manufacturing, nuclear reactors and periodic heat exchanges process.

威廉姆森流体混合纳米粒子悬浮液中的非傅里叶热通量和焦耳耗散

摘要

这项工作的主要关注点是分析混合纳米粒子在通过对流加热的加热缸改善威廉姆森流体的热行为方面的性能。石墨烯和磁性氧化物同时被威廉姆森液体扩散。这种混合纳米流体（石墨烯、威廉姆森流体和磁性氧化物的混合物）的高效热特性模型被应用于通过一组关于动量和能量守恒的复杂数值表达式来模拟这种热传递及其结果。方程通过 MATLAB 中的 bvp4c 函数进行数学确定。进行了这种参数分析，当注意到混合纳米颗粒（磁性氧化物和石墨烯）时，威廉姆森流体的热行为得到了重要的增强。混合纳米威廉姆森流体（磁性氧化物，石墨烯和威廉姆森流体的组合）的壁热通量基本上高于石墨烯和威廉姆森流体混合物的热行为。当流体参数和磁场升高时，该壁剪切应力会增加。这种热传递速率提高了热辐射，并且毕奥数也提高了。这些混合纳米流体在纳米药物输送系统、微制造、核反应堆和周期性热交换过程等新兴产业中具有多种实用功能。
