Effects of Viscosity-Variation and Viscous Dissipation in Microchannels of the MTPV Systems

Article Preview

Abstract:

Heat transfer and fluid flow in the microchannel cooling passages of plane cell type MTPV systems are numerically investigated. The Finite Volume method is adopted for the governing equations discretization; The SIMPLE method is applied to deal with the linkage between pressure and velocities. Numerical results confirm that the effects of viscous dissipation and variable viscosity could not be neglected. Influence of viscosity-variation with temperature of water and viscous dissipation on the flow and heat transfer characteristics of the microchannel cooling passage was discussed. The computer simulations were validated by the analytical solution results.
