An analysis was made of the transport processes occurring when a fuel-oxidizer mixture is injected through a porous plate into the boundary layer in an air stream. Since the mass velocity of the oxidizer is lower than that required for stoichiometric mixture formation, combustion cannot take place inside the plate. The additional required oxygen flows into the combustion zone from the air stream. The reaction zone was considered to be located at a position where the concentration is stoichiometric. The analysis yielded expressions correlating the location of the reaction front with the fueloxidizer ratio at the inlet to the porous plate and with the Nu and Re numbers of the air stream. The location of the reaction front was found to be a function of the fuel oxidizer ratio, the injection rate, and the Schmidt number. The heat transfer coefficient decreased as the injection rate increased.
