Abstract

Abstract In the current study, we numerically analyze the significance of motile microbes on the magnetohydrodynamic steady convective streams of tangent hyperbolic (TH) nanofluid flow across an elastic nonlinearly stretching surface of an irregular thickness. The consequences of an external magnetic field, thermal radiation, and thermal conductivity are also examined on the TH nanofluid. The governing system of equations (nonlinear set of partial differential equations) is transfigured into a system of ordinary differential equations (ODEs) by using the similarity variable conversions. Furthermore, the reduced form of nonlinear ODEs is numerically computed through the parametric continuation method (PCM) using MATLAB software. The relative evaluation is carried out to authenticate the numerical outcomes. It has been observed that the energy field accelerates with the Rayleigh number, Weissenberg number, and Brownian motion. The mass propagation ratio improves with the effect of activation energy and decreases with the influence of chemical reactions. Furthermore, the motile microbes’ profile declined with the outcome of the Peclet and Lewis numbers. The skin friction increases up to 7.3% with various magnetic values ranging from 0.5 to 1.5. However, the energy transfer rate declines to 5.92%. The thermal radiation boosts the energy propagation rate and flow velocity by up to 11.23 and 8.17%, respectively.
旋回微生物对MHD切线双曲纳米流体在弹性细长表面上流动的意义:数值分析
摘要在本研究中,我们用数值方法分析了移动微生物对正切双曲(TH)纳米流体流过不规则厚度的弹性非线性拉伸表面的磁流体力学稳定对流流的意义。外部磁场、热辐射和导热性的影响也在TH纳米流体上进行了研究。利用相似变量变换将控制方程组(非线性偏微分方程组)转化为常微分方程组(ode)。在此基础上,利用MATLAB软件通过参数延拓法(PCM)对非线性微分方程的化简形式进行了数值计算。对数值结果进行了相应的评价。已经观察到能量场随瑞利数、魏森伯格数和布朗运动加速。质量传播比随活化能的影响而增大,随化学反应的影响而减小。此外,随着Peclet和Lewis计数的结果,活动微生物的分布也有所下降。当磁性值在0.5 ~ 1.5之间变化时,表面摩擦力可增加7.3%。能量转移率下降到5.92%。热辐射可使能量传播速率和流速分别提高11.23%和8.17%。
