摘要

在这项工作中,我们考虑不可压缩流体在半无限圆柱上的稳定流动。圆柱体嵌入多孔介质中,以非线性速度垂直运动。利用自相似变换,由控制运动的偏微分方程得到一个常微分方程组。在得到遗漏的初始条件后,对该常微分方程组进行了数值求解。对于线速度情况,该问题已得到了解析解。文中给出了这种情况下的数值和分析结果,以验证所采用的数值方法。

Boundary Layer Flow Over a Vertical Cylinder Embedded in a Porous Medium Moving With Non Linear Velocity
In this work, we consider a steady flow of an incompressible fluid over a cylinder which is semi-infinite. The cylinder is embedded in a porous medium and is considered to move vertically with nonlinear velocity. A system of ordinary differential equations is obtained from the partial differential equations governing the motion using a self-similarity transformation. Such system of ordinary differential equations is solved numerically after obtaining the missed initial conditions. The problem has been solved analytically for the linear velocity case. Numerical and analytical results for such case are given to validate the numerical method used.

期刊介绍: WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
