A computational study of viscous flow between concentric and eccentrically rotating cylinders in presented in which the effect of viscous dissipation is taken into account.
The inner cylinder is assumed to be rotating at constant speed with respect to the outer one.
We assume a no-alip boundary condition for the velocity on both walls. The temperature of the fluid is assumed to be constant on the cylinders and its distribution is assumed to be governed by both conduction and convection, with a supplementary soure of energy du to the effects of viscous dissipation. The viscosity is assumed to be varies with temperature. The space discretization is based on piecewise linear finite elements, with velocity stabilization in case of the eccentrically cylinders. The method of characteristics is used for time integration in the eccentrically problem. Numerical results illustrate the efficienty of the adopted approach.
