In order to investigate the separation mechanism and provide some guidance for the separator design,the single-phase flow field of the bubble separator for the Molten Salt Reactor is simulated numerically by Reynolds Stress Model.The results show that a low-pressure and high-velocity region is induced under the obstruction of the guiding vanes in the flowing channel and the tangential velocity distribution resembles the Rankine vortex.Besides,the swirl number along the axial position increases first and then decreases due to the improvement of the first light phase outlet.Moreover,the effects of the key structure parameter of the generating swirler including deflection angle,the guiding vane number and the hub ratio on the flow field are investigated and their sensitivity analyses are conducted at the same time.It demonstrates that the deflection has the largest influence on the flow field and the hub ratio is the second.
