摘要

本文重点研究了含陀螺策略微生物的MHD非牛顿纳米流体在多孔介质中通过板、楔和滞止点的二维稳态流动的数值干预。主要研究了Peclet数、生物对流、布朗运动、热泳动和产热的影响,以巩固热流体和纳米流体浓度守恒方程,该方程具有被动控制的边界条件,适用于流过板、楔和驻点的三种不同几何条件。通过考虑不同相关参数的影响,即热电泳、布朗运动、普朗特数、产热、化学反应、生物对流和磁性参数,图形分析了动量、温度、纳米颗粒体积分数、可运动微生物分布密度以及局部努塞尔和可运动微生物数量的结果。利用相关的相似变换得到常微分方程组,并基于射击技术,利用MATLAB软件Bvp4c对方程组进行数值求解。

Heat Generation and Thermal Radiation Effects on Magneto Hydrodynamics Non Newtonian Casson Nanofluid with Gyro Tactic Microorganisms Over a Plate, Stagnation and Wedge Through Porous Media
The numerical interventions of two dimensional steady flow of MHD Non-Newtonian nanofluids containing the gyro-tactic microorganisms through porous media over a plate, wedge, and stagnation point are highlighted in this paper. Mainly the Peclet number, bioconvection, Brownian motion, thermophoresis, and heat generation impacts are addressed to consolidate thermal and nanofluid concentration conservative equations with passively controlled boundary conditions for three different geometrical conditions of flow over a plate, wedge, and stagnation point. By considering the impacts of the varying pertinent parameters, namely thermophoresis, Brownian motion, Prandtl number, heat generation, chemical reaction, bio convectional and magnetic parameters, results are analysed graphically for the momentum, temperature, nanoparticle volume fractions, and the density of motile microorganisms profile, as well as the local Nusselt and motile microorganism numbers. Relevant similarity transformations are used to obtain the system of ordinary differential equations and the equations are solved numerically by using Bvp4c via MATLAB based on the shooting technique.
