Effect of Ramped Wall Temperature on Unsteady Mixed Convection Flow of Rotating Second Grade Fluid in Porous Medium

The effects of ramped wall temperature, rotation and porosity on mixed convection flow of incompressible second grade fluid are studied. The momentum equation is modelled in a problem of rotating fluid with constant angular velocity subjected to initial and oscillating boundary conditions. The energ...
