Abstract

In this study, a steady magnetohydrodynamic (MHD) flow due to stretchable rotating disk in the presence of gyrotactic microorganisms is investigated. The governing equations modeling the flow are solved numerically using the newly introduced simple iteration method (SIM) that seeks to linearize a system using relaxation technique that effectively decouples the system. To verify the convergence and accuracy of the method, solution error and residual error analysis are carried out, respectively. The obtained results suggest that the SIM is a highly efficient method that produces convergent and highly accurate solutions. The effects of various parameters as well as combined parameter effects on the solution profiles are also investigated. An increase in the Hall and permeability parameters leads to a corresponding rise in the microorganism?s density and nanoparticle volume fraction.

可拉伸旋转盘对纳米流体流动的数值模拟
在这项研究中,研究了在回旋微生物存在的情况下,由可拉伸旋转盘引起的稳定磁流体动力学(MHD)流动。采用新引入的简单迭代法(SIM)对流的控制方程进行了数值求解,该方法寻求使用松弛技术对系统进行线性化,从而有效地解耦系统。为了验证该方法的收敛性和准确性,分别进行了求解误差和残差分析。结果表明,该方法是一种高效的求解方法,求解结果收敛且精度高。还研究了各种参数对溶液轮廓的影响以及组合参数对溶液轮廓的影响。霍尔参数和渗透率参数的增加导致微生物?S密度和纳米颗粒体积分数。
