Solutions of Navier-Stokes NS equations were obtained for burning rate Nu and temperature distributions for a flat PMMA plate using an iterative method to impose steady-state, pyrolysis kinetics at the surface. The NS solutions show that Nu depends on two parameters-Reynolds number Re and air velocity-unlike the classical solutions, which include the boundary layer approximations. The NS solutions are compared with experiments to show that the curvature and in-depth heat transferpyrolysis effects are significant within the pyrolysis zone at large and small bum times, respectively.
