Abstract

A conceptual boundary level experiment of heat and mass transfer flow in an MHD viscous nanofluid containing gyrotactic microorganisms around a stretching cylinder has been evaluated in this work. The governing equations of the flow have been executed by the boundary layer phenomena. The primary non-linear PDEs have been turned into a dimensionless form via application of suitable dimensionless variables. The resulting non-similar dimensionless differential equations have been resolved by the EFDM with the help of FORTRAN software version 6.6a. Stability and convergence criteria analysis enabled obtaining the convergent solutions. The consequences of numerous parameters such as the Magnetic parameter, Brownian motion parameter, Thermophoresis parameter, Lewis number, Micro-organism Lewis number, and Bio-convection parameter on the flow have been investigated, and the outcomes have been demonstrated graphically. Finally, the current outcomes were compared with the previously published results.

含有回旋微生物的非稳态 MHD 粘性纳米流体流通过圆柱形外部区域

摘要

在这项工作中，已经评估了在拉伸圆柱体周围含有回旋微生物的 MHD 粘性纳米流体中传热和传质流动的概念边界水平实验。流动的控制方程已由边界层现象执行。通过应用合适的无量纲变量，初级非线性偏微分方程已转化为无量纲形式。EFDM 在 FORTRAN 软件 6.6a 版的帮助下求解了所得的非相似无量纲微分方程。稳定性和收敛准则分析能够获得收敛解。许多参数的结果，例如磁参数、布朗运动参数、热泳参数、路易斯数、微生物路易斯数、对流动的生物对流参数进行了研究，并以图形方式展示了结果。最后，将当前结果与之前公布的结果进行了比较。
