Wall Curvature Effects on External Burning in Supersonic Flow

The present work is based on the very ingenious models that the Billig school has produced and developed over the last two decades concerning combustion in the viscous mixing region along surfaces exposed to a supersonic external flow. Here two particular areas have been addressed. First, the strong wall curvature effect on enlargement of the set of possible heating parameters is shown. External burning on curved surfaces appears to be more promising possibility than that on straight walls. Second, for applications on curved surfaces, the most striking novelty in contrast to the straight wall cases, that is the necessity of reading the wall slope in terms of the integration variable has been solved. The use of boundary value problem codes to recognize the throat position on the wall and to obtain proper values of the parameters at the inflow station have proven to be very successful and useful.
