Abstract

Abstract

In order to predict the gas-liquid two-phase flow behavior in a baffle, OpenFOAM based Euler-Lagrangian method was used to simulate the two-way coupling flow of discrete and continuous phases in a baffle, with liquid droplets as the discrete phase and gas flow as the continuous phase. The discrete phase is subject to the drag force, and the continuous phase is simulated using the standard k-ε model and the standard k-ω SST model respectively. This article introduces grid meshing, post-processing of Lagrangian particle coordinates generated by OpenFOAM, and a program based on OpenFOAM for baffle steam water separation efficiency. The continuous-phase flow field, continuous-phase velocity field and steam water separation efficiency of different turbulence models under different grids are calculated and compared with the experimental data. The results show that the turbulence model has a greater impact on the results than the grid, whether it is continuous phase or discrete phase, and the calculation results of k-ω SST model are more accurate. The model can predict the separation efficiency of large diameter droplets accurately, but cannot predict the separation efficiency of small diameter droplets accurately enough.
