| Abstract: | The computational fluid dynamics (CFD) software was used, and the mathematical model of the distributor was established by using the Euler-Euler multiphase flow model and the standard turbulence model with the real liquid and gas as the material system. Based on the gas phase inlet structure, liquid phase inlet arrangement and stream breaker，the structural optimization and performance analysis of the overflow type distributor were carried out by comparing the mathematical model with reported data. The results show that, compared with the basic configuration, the distribution unevenness of the new optimized overflow type distributor is reduced by 9.4% and the spraying area is increased by 69.2% under the simulated working conditions, and the distribution effect of the distributor is effectively improved. |
