Abstract

By assuming similarity, the porous matrix flow is decoupled from the boundary layer flow and the surface temperature equated to the saturation temperature of the coolant. The porous flow energy model, which assumes thermal equilibrium between the coolant and matrix, is justified on the basis of pore size. Three-dimensional steady-state results are presented and show isothermal approximations to be substantially in error. Transient one-dimensional results indicate that control of coolant flow provides greater stability than control of coolant pressure.
