摘要

研究了Oldroyd - B纳米流体铁磁流动引起的传热传质现象。引入热源、热辐射、活化能等附加热源特征,扩展了流动问题的动态性。流源为磁偶极子冲击下的运动拉伸面。实现了对流边界条件。利用Boungrino纳米流体模型观察了热泳动和布朗运动的结果。考虑流动假设的问题的数学模型将被转换为非量纲形式。采用数值射击技术进行近似模拟。在验证了解的精度后,给出了参数变化问题的物理动态。注意到由于铁流体动力相互作用参数的影响,速度剖面减小。由于松弛时间常数和铁流体动力相互作用参数的增加,热剖面得到了增强。此外,延迟时间常数参数降低了浓度分布。

Development of convective heat transport in nanofluid flow of Oldroyd‐B model with magnetic dipole moment
The phenomenon of heat as well as mass transfer due to ferromagnetic flow of Oldroyd‐B nanofluid is addressed. The additional thermal source like heat source, thermal radiation, and activation energy features has been implemented to extend the dynamic of flow problem. The source of flow is moving stretching surface with magnetic dipole impact. The convective boundary conditions are implemented. The Boungrino nanofluid model is used to observe the thermophoresis and Brownian motion consequences. The mathematical modeling of problem in view of flow assumptions will be converted into the non‐dimensional form. The numerical shooting technique will be implemented for presenting the approximate simulations. After verifying the solution accuracy, the physical dynamic of problem with variation of parameter is presented. It is noticed that the velocity profile reduces due to ferrohydrodynamic interaction parameter. An enhanced thermal profile is observed due to relaxation time constant and ferrohydrodynamic interaction parameter. Furthermore, the concentration profile reduces for retardation time constant parameter.

期刊介绍: ZAMM is one of the oldest journals in the field of applied mathematics and mechanics and is read by scientists all over the world. The aim and scope of ZAMM is the publication of new results and review articles and information on applied mathematics (mainly numerical mathematics and various applications of analysis, in particular numerical aspects of differential and integral equations), on the entire field of theoretical and applied mechanics (solid mechanics, fluid mechanics, thermodynamics). ZAMM is also open to essential contributions on mathematics in industrial applications.
