ABSTRACT

       A simplified algebraic Reynolds stress model (ASM) was developed and used to simulate strongly swirling confined flows. The k-e turbulence model was also employed in the present simulation for comparison. For the flows compared, the predicted results of gas tangential and axial velocities based on this model are in good agreement with measurements. The computation shows that the ASM is superior to the k-e model in capturing the stabilising effect of the swirl.
