Abstract
Numerical simulations of kerosene combustion in a dual mode supersonic combustor (Mach 2.5) have been carried out. The combustor has wall mounted injectors for the first stage and ramp based injectors for the second stage. The simulations have been performed using the commercial software FLUENT. Spalart-Allmaras model has been used for modeling turbulence and single step finite rate chemistry has been used for modeling the C12H 26/Air kinetics. The grid has been refined to achieve average value for wall Yplus less than 29. The predicted static pressure profile along the centerline of the combustor is shown to agree well with the experimental data for different injection schemes. Details of the flowfield inside the combustor are presented and discussed.
