Analysis of the chemically reacting laminar boundary layer during hybrid combustion

The chemically reacting boundary layer over a fuel plate was analyzed to show the effect of thermodynamic coupling at the solid-gas interface. The fuel is assumed to undergo surface pyrolysis with subsequent reaction with the freestream oxidizer at a flame sheet. Computed values of species and temperature profile, flame sheet and boundary-layer thickness, as well as surface blowing rates are presented for a variety of cases of stoichiometry, energy feedback, and pressure gradient. Although similarity approximations were utilized, the analysis compares favorably with results of regression studies during hybrid combustion.
