Calculo de un frente de llama laminar por un método espectral de colocación

Abstract

A one-dimensional plane flame computation is carried out. The plane flame is propagating in a gaseous medium containing only a small amount of reacting gas. The non-linearity of Arrhenius law introduces the main difficulty due to presence of high-gradients in the solution. Physicaly, this fact means that the reaction is produced in a smallregion. In this work a spectral collocation method is proposed to avoid this problem.It is based in a domain descomposition adapted to the physical situation o the flame. This allows a good profile resolution.
