NUMERICAL-SIMULATION OF CONJUGATE HEAT-TRANSFER UNDER CONDITIONS OF TRANSPIRATION COOLING OF CYLINDRICAL FRONT EDGE

A conjugate mathematical model, including the equations of filtration and heat transfer in a porous wall and the equation of boundary layer on its surface, is used to investigate the heat and mass transfer unde r conditions of flow past a cylindrical front edge with a porous envel ope. The effect of longitudinal filtration and thermal conductivity on the characteristics of transpiration cooling is treated. Special atte ntion is given to the nonuniformity of distribution of the parameters of conjugate heat transfer in the longitudinal direction.
