A LES Scheme for Mixing and Reacting Flow Inside a Combustor
Álvaro De Bortoli (Federal University of Rio Grande do Sul)
The present work develops a LES scheme for the solution of mixing and reacting flows inside a combustor. The model considers the overall, single step, irreversible reaction between two species; the reaction rate is governed by the Arrhenius law. Numerical tests, based on the finite difference explicit Runge-Kutta five-stage scheme, for third order time and fourth order space approximations, are carried out for Damköhler 300, Zel'dovich 10, Heat Release 10 and Schmidt and Prandtl both equal to 0.9 and the results contribute to understand the mixture-reaction behaviour for the reacting flow inside a combustor.
