摘要

主要目标是在热和质量传输、抽吸和注入以及对流边界条件下,对添加了纳米颗粒的威廉姆森流体进行数值合成,该流体在均匀的横向磁场中指向垂直锥体。对于这种特殊的流体流动,通过利用相似变换,将偏微分方程转换为普通微分方程。计算这类方程及其合适的边界需要结合射击策略的龙格-库塔技术。大量参数的函数在现场文件中用图形表示和评估。结果显示了局部皮肤摩擦、局部努塞尔数和局部舍伍德数以及流动约束的变化值。最后,将结果与之前发表的作品进行了比较,发现结果非常一致。

Numerical study of MHD Williamson-nano fluid flow past a vertical cone in the presence of suction/injection and convective boundary conditions
The primary objective is to perform a numerical synthesis of a Williamson fluid that has nanoparticles added to it and is directed toward a vertical cone in a uniform transverse magnetic field, under heat and mass transport, suction and injection, and convective boundary conditions. For this particular fluid flow, by utilising similarity transformations, the partial differential equations are transformed into ordinary differential equations. Calculating these kinds of equations with their suitable bounds requires the Runge–Kutta technique in combining a shooting strategy. The functions of a vast number of parameters are graphically represented and assessed on flow field profiles. The results show the local skin friction, local Nusselt number, and local Sherwood number and the changing values of the flow constraints. Finally, the results are compared to those from the previously published works and found to be in good agreement.
