This study explores the magnetohydrodynamic fluid flow through two rotating plates subjected to the impact of microorganisms. The nanoparticles of copper and alumina are mixed with water for formulating hybrid nanofluid with new combination . This new combination augments the thermal conductivity of pure fluid. The flow is influenced by the coupled effects of Dufour and Soret diffusions. The joined effects of chemically reactive activation energy have been incorporated in the mass transportation equation. A constant magnetic field has been employed to the flow field with strength in normal direction to the plates. The equations that controlled fluid flow have been transferred to dimension-free form by implementing suitable set of variables. The influence of the different factors has been examined theoretically by employing the graphical view of different flow profiles. It has been concluded in this work that, linear velocity has declined by augmentation in magnetic factor and rotational parameter whereas these factors have enhanced microrotational profiles of fluid. Higher values of radiation parameter, Dufour number, and volumetric fractions have augmented fluid’s thermal profiles. The concentration of fluid has been retarded with upsurge in Soret number and chemical reaction parameter whereas growth in activation energy parameter has supported the upsurge in concentration. The rate of motile microorganisms has retarded by upsurge in the values of Lewis and Peclet numbers. It has been noticed that when , and varies from 0.2 to 0.6 then in case of nanofluid, skin friction changes from 0.288 to 0.633 at and from 0.292 to 0.646 at and in case of hybrid nanofluid the variations in skin friction are from 0.328 to 0.646 at and from 0.335 to 0.703 at .

耦合 Dufour 和 Soret 对混合纳米流体流通过受化学反应阿伦尼乌斯活化能影响的旋转通道的影响

本研究探讨了磁流体在受到微生物影响的情况下流过两个旋转板的情况。将铜和氧化铝的纳米粒子与水混合以配制具有新组合的杂化纳米流体. 这种新组合增强了纯流体的导热性。流动受 Dufour 和 Soret 扩散的耦合效应影响。化学反应活化能的联合效应已被纳入质量传输方程。对具有强度的流场采用恒定磁场在板的法线方向。通过实施合适的变量集,控制流体流动的方程式已转换为无量纲形式。不同因素的影响已经通过采用不同流动剖面的图形视图进行了理论上的检验。在这项工作中得出的结论是,线速度因磁因子和旋转参数的增加而下降,而这些因素增强了流体的微旋转剖面。辐射参数、Dufour 数和体积分数的较高值增强了流体的热分布。流体的浓度随着 Soret 数和化学反应参数的上升而延迟,而活化能参数的增长支持了浓度的上升。活动微生物的速度因 Lewis 和 Peclet 数值的激增而减慢。人们注意到,当并且在 0.2 到 0.6 之间变化,然后在纳米流体的情况下,皮肤摩擦从 0.288 变为 0.633从 0.292 到 0.646在混合纳米流体的情况下,表面摩擦的变化在 0.328 到 0.646 之间从 0.335 到 0.703.
