MHD Hele-Shaw flow of an elasticoviscous fluid through porus media

In the present paper Hele-Shaw flow of an elastico-viscous Maxwell conducting fluid between two parallel walls at z = ± h past a fixed circular cylinder x2+y2=a2.-h < z < h under time dependent pressure gradient through porous medium in the presence of magnetic field applied perpendicular to the flow of the fluid is investigated. Expressions for components of velocity are obtained for periodic motion by using Laplace transform technique. The velocity field F(t,x) versus t and x is discussed with the help of graphs for different values of K, M and S. (author). 9 refs
