| Abstract: | A full form of the improved algebraic Reynolds stress model(ASM)is employed to simulate swirling turbulent flows in a swirl combustor with two coaxial jets in this paper.The calculated results are compared with the measured test data and those predicted by the k-ε model and a simplified form of the improved ASM.It is shows that better predictions are achieved by the full form of the improved ASM,which are closer to the measured data than those obtained by the other two models. |
