Abstract Annular distributor plays an important role in achieving uniform distribution in the shell of multitubular fixedbed reactor.The static pressure distribution characteristics and the influence of the structure parameters of annular distributor such as inlet number and outlet number on the uniform performance were analyzed based on the calculated fluid dynamic(CFD)method.The simulation results showed that when outlets of the same size were opened,and other structure parameters and import condition kept unchanged,decreasing outlet number in a certain range and increasing inlet number were beneficial to uniform distribution of fluid inside the annular distributor.Moreover,according to the pressure characteristics in annular distributor,the fluid distribution depends on the pressure drop of main channel and the pressure drop of outlets.Based on simulation results,U was defined as the ratio of the pressure drop of outlets to the total pressure drop between inlet and outlet.If  U  was at 0.95—1.06,that means the fluid has been uniformly distributed even outlets of the same size were opened.
