A comprehensive multi-scale method of model reduction and analysis for reactive flow
… The numerical simulation for reactive flow with detailed chemistry is challenging, one of the
main reasons is that the highly nonlinear chemical source term together with diffusion and
convection terms in Navier-Stokes equation contributes to a wide range of time scales, which
impose a severe stiffness in the simulations. The traditional approaches to resolve the … The
current work develops a comprehensive method to analyze characteristic time scales for
reaction, convection and diffusion. Firstly, using the G-Scheme Participation Index (GPI) the …
