The intention of this study is to carry out a numerical investigation of time-dependent magneto-hydro-dynamics (MHD) Eyring-Powell liquid by taking a moving/static wedge with Darcy-Forchheimer relation. Thermal radiation was taken into account for upcoming solar radiation, and the idea of bioconvection is also considered for regulating the unsystematic exertion of floating nanoparticles. The novel idea of this work was to stabilized nanoparticles through the bioconvection phenomena. Brownian motion and thermophoresis effects are combined in the most current revision of the nanofluid model. Fluid viscosity and thermal conductivity that depend on temperature are predominant. The extremely nonlinear system of equations comprising partial differential equations (PDEs) with the boundary conditions are converted into ordinary differential equations (ODEs) through an appropriate suitable approach. The reformed equations are then operated numerically with the use of the well-known Lobatto IIIa formula. The variations of different variables on velocity, concentration, temperature and motile microorganism graphs are discussed as well as force friction, the Nusselt, Sherwood, and the motile density organism numbers. It is observed that Forchheimer number Fr decline the velocity field in the case of static and moving wedge. Furthermore, the motile density profiles are deprecated by higher values of the bio convective Lewis number and Peclet number. Current results have been related to the literature indicated aforementioned and are found to be great achievement.
本研究旨在通过采用具有达西 - 福希海默关系的移动/静止楔形物,对随时间变化的磁流体动力学(MHD)埃林 - 鲍威尔液体进行数值研究。考虑到即将到来的太阳辐射,纳入了热辐射,并且还考虑了生物对流的概念,以调节悬浮纳米颗粒的无规律运动。这项工作的新颖之处在于通过生物对流现象使纳米颗粒稳定。在纳米流体模型的最新修订版中,结合了布朗运动和热泳效应。取决于温度的流体粘度和热导率是主要因素。通过适当的方法,将包含带有边界条件的偏微分方程(PDEs)的极其非线性方程组转换为常微分方程(ODEs)。然后使用著名的洛巴托IIIa公式对 reformed 方程进行数值运算。讨论了速度、浓度、温度和活动微生物图上不同变量的变化,以及力摩擦、努塞尔特数、舍伍德数和活动密度生物体数。观察到在静止和移动楔形物的情况下,福希海默数Fr会降低速度场。此外,较高的生物对流刘易斯数和佩克莱特数会使活动密度分布降低。当前结果已与上述文献相关,并且被发现是一项重大成就。 (注:原文中“reformed”疑有误,可能是“transformed”之类的词,这里按原文翻译)
