Abstract

Purpose

This paper aims to numerically examine the impact of gyrotactic microorganisms and radiation on heat transport features of magnetic nanoliquid within a closed cavity. Thermophoresis, chemical reaction and Brownian motion are also considered in flow geometry for the moment of nanoparticles.

Design/methodology/approach

Finite element method (FEM) was depleted to numerically approximate the temperature, momentum, concentration and microorganisms concentration of the nanoliquid. The present simulation was unsteady state, and the resulting transformed equations are simulated by FEM-based Mathematica algorithm.

Findings

It has been found that isotherm patterns get larger with increasing values of the magnetic field parameter. Additionally, numerical codes for rate of heat transport impedance inside the cavity with an increasing Brownian motion parameter values.

Originality/value

To the best of the authors’ knowledge, the research work carried out in this paper is new, and no part is copied from others’ works.

带有陀螺仪微生物的封闭舱内热辐射纳米流体传热分析

目的本文旨在通过数值方法研究陀螺微生物和辐射对封闭空腔内磁性纳米液体热传输特征的影响。本文采用有限元法（FEM）对纳米液体的温度、动量、浓度和微生物浓度进行了数值模拟。本模拟为非稳态模拟，并通过基于有限元法的 Mathematica 算法模拟所得到的转换方程。此外，随着布朗运动参数值的增加，空腔内热传输阻抗率的数值代码也在增加。原创性/价值据作者所知，本文的研究工作是全新的，没有抄袭他人作品的部分。
