Abstract

A novel compressible Navier-Stokes solver for chemically reacting flows is proposed with an explicit Navier-Stokes predictor step and a semi-implicit corrector step for stiff chemical source terms. A modular code to read chemical mechanisms in the Chemkin format is coupled to the solver allowing the ability to simulate multiple fuels with minimal effort. This segregated approach allows the independent modification of the Navier-Stokes solver and the chemical source term integration algorithm. Validation of a well-stirred reactor, an unsteady unstrained diffusion flame, and results from a lifted non-premixed flame in vitiated coflow in two and three dimensional configurations are presented.
