Pyrolysis and Boundary Layer Combustion of a Non-Charring Solid Plate Under Forced Flow

Abstract

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 transfer/pyrolysis effects are significant within the pyrolysis zone at large and small bum times, respectively.
