The fluid-dynamical and thermal features of transpiration cooling of the porous injector are theoretically studied by solving the governing equations of fluid flow and heat transfer in porous medium. First, the flow characteristics of the porous injector is obtained in relation to the two-dementional fluid-dynamical boundary conditions. By using this result, the thermal features of transpiration cooling of the porous injector for TC-1002 combustor are investigated theoretically to obtain the effects of the relevant factors on it such as the viscous coefficient of porous flow, the thermal conductivity of porous material, the heat transfer coefficients of the coolant flow and the combustion gas and the porosity of porous medium.
