Oscillatory Free Convective Flow of Viscoelastic Fluid Through Porous Medium in a Rotating Vertical Channel

A theoretical analysis of an oscillatory viscoelastic, incompressible and electrically conducting fluid in an infinite vertical porous channel is presented. The entire system rotates about the axis normal to the plane of the plate with uniform angular velocity Ω\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \Upomega $$\end{document}. A closed form solution for the velocity, temperature and skin friction are obtained. Results are presented through graphs and table for the various values of rotation, viscoelastic, permeability and frequency of oscillation parameter and discussed in detail.
