Abstract
In this study, a newly proposed pressure correction method coupled with DBS drag force model was used to simulate the gas-liquid flow in a bubble column, which combines Eulerian-Eulerian approach to simulate gas-liquid flow under elevated pressure conditions. This further verifies the accuracy of the model and expands its application range. The gas holdup and velocity distributions of different models were compared, and the performance of the new model was similar to that of Yan et al., while the model of Tran et al. was not sensitive to the influence of the pressure in this study. It was found that the drag model using the new pressure correction method showed the best consistency.
