摘要

本文研究了磁性麦克斯韦流体(包括生物纳米流体)在旋转盘吸入/注入效应下的达希安-福赫海默(Darcian Forchheimer)。热辐射、热源/散热和化学反应都被考虑在内。在热量和浓度条件中引入了对流和零热质量通量。利用相似性替代法将支配系统的非线性偏微分方程转换为常微分方程。随后使用 Bvp4c 方法对这些变化后的方程进行数值求解。我们进行了全面的分析,将目前的研究结果与之前发表的出版物进行了比较,结果表明我们的研究成果达到了令人瞩目的水平。陀螺仪微生物的影响被纳入用于描述生物对流的模型中。考虑到热量和质量通量为零的对流热条件,假定旋转表面已为纳米流体壁吸或注入的可能性做好了准备。当前工作的主要发现是径向和轴向速度随着德博拉数值的增大而减小,同时随着拉伸变量的增大而增大。预计这项研究将有助于更好地了解各种物理领域的传热机制。

Bio-convection Maxwell nanofluid through Darcy Forchheimer medium due to rotating disc in the presence of MHD

The current paper examines the Darcian Forchheimer for the magneto-Maxwell fluid comprising of bio-nanofluid in the suction/injection effect due to rotating disk. Thermal radiative, heat source/sink, and chemical reaction are taken into account. Convective and zero heat mass flux have been introduced in the thermal and concentration conditions. The nonlinear partial differential equations that govern the system are converted into ordinary differential equations using a similarity substitution. These changed equations are subsequently solved numerically using the Bvp4c method. A thorough analysis is conducted, comparing the current findings with previously published publications, resulting in a remarkable level of achievement. The implications of gyrotactic microorganisms are incorporated into the model that is used to describe the bioconvection. Given the conditions of convective heat with zero heat and mass flux, it is presumed that the surface of the rotating is prepared for the possibility of nanofluid wall suction or injection. The main finding of the current work is radial and axial velocity is depreciated with enlarging values of Deborah number while rise with stretching variable. This study is anticipated to be beneficial in gaining a better understanding of the mechanisms involved in heat transfer in a variety of physical sectors.
