Reaction-diffusion manifolds (REDIM) based on a simple gradient estimate are employed to simulate methane/air turbulent flames. Validation is performed for non-premixed laminar flames. A RANS/transportedPDF strategy for the simulation of turbulent reacting flows is presented and used to validate the proposed model. Results show that the simple gradient guess is enough to simulate turbulent flames at moderate Reynolds number, which demonstrates the suitability of REDIM as reduced kinetic model in reactive flows.
