A new kind of stabilizer—ceramic stabilizer—is applied in the afterburner of an aero-engine. In contrast to a traditional stabilizer, fuel can be supplied from its ceramic surface, so a more stable performance can be expected from the flame behind the stabilizer. A pressure-based, unstructured grid solver is developed by CFD Research Corporation. An evaporation model for fuel droplets is developed to predict the evaporation rate. Numerical simulations concerning flow and heat transfer are conducted to predict the spray evaporation, and the chemical reactions in the fuel in the after burner. The focus of this paper is the stability improvement from this new kind of ceramic stabilizer.
