Abstract: Using three-dimensional model, the cross-shaped baffler distributor was systematically simulated by CFX fluid mechanics modeling software. The impact of size of upon cover of inner sleeve on degree of uniformity of gas distribution of feeding distributor was emphasized. Meantime, the impact of the number and size of guide plate on performance of entrainment and pressure drop of the distributor was researched. At last, the structural parameters of excellent performanced cross-shaped baffler distributor was confirmed and so as to support direction for structural optimization of the distributor.
