The FLUENT computational fluid dynamic code has been used to aid design of the Westinghouse Multi-Annular Swirl Burner (MASB). After successful comparison of FLUENT predictions to test data, design studies using FLUENT have indicated that backwall holes are unnecessary in the MASB design. FLUENT was then used to study the adaptation of the MASB design to the Power Systems Development Facility (PSDF). Preliminary steady-state and transient simulations of the propane-fueled start-up process indicate that flame structure is dependent on the choice turbulence closure and the resultant variation in swirl levels and recirculation zones. Due to the effect of duct geometry on swirl dissipation, a more accurate representation of the transition duct connecting the MASB to the turbine will be needed to better describe the flame structure
