Abstract

Numerical analysis on an aerodynamic structure of a laminar boundary layer diffusion flame over a horizontal flat plate has been done, taking into account a local pressure gradient in a boundary layer. The calculations were carried out, using a 'Simpler' algorithm. A flame sheet approximation was applied to describe the combustion process. When the flame is formed, the pressure field in the boundary layer is varied locally and the streamwise pressure gradient is formed even if effects of gravity or of acceleration of the free stream velocity are not taken into account. This streamwise pressure gradient induces the velocity overshoot. Furthermore, the numerical calculation, taking into account the effects of gravity and the free stream acceleration in the present equations, shows good agreement with the corresponding experimental results.
