A Flame Zone Model for Chemical Reaction in a Laminar Boundary Layer with Application to the Injection of Hydrogen-Oxygen Mixtures,
Abstract
An analysis for the prediction of the boundary layer chaacteristics i derived for the case of a chemically reacting gas injected through a porous surface. It i asumed that the flow is steady and laminar with zero pressure gradient. The analysis is based on a model for combustion which utilies the concept of an ignition temperature to distinguish between regions of frozen and equilibrium flow; the model is referred to as the flme zone model. Results of several numerical exaples are presented to demonsrate the use of this model. These include the heat transfer rates to the porou surface as well as temperature and concentration distibutions through the boundary layer. Calculations are carried out for conditions corresponding to hypersonic flight and to typical hypersonic wind tunnel flows and to injected gases consisting of either hydrogen or hydrogen-oxygen mixtures.
