Numerical Investigation of Non-Newtonian laminar Flow Over Rotating Cylinder

Non-Newtonian laminar flow over rotating cylinder is studied numerically. We have simulated non Newtonian flow (the both shear thinning and shear thickening) using power law model and investigated the variation of important parameters such as power index, rotating speed and inlet Reynolds number effects. Then intensive dependence of thermal and drag coefficients to these parameters is recognized. Increasing Reynolds number results in increasing the thermal and drag coefficients. Also increasing power index, due to boundary layer growth, thermal coefficient decreased but drag coefficient enhanced.
