Abstract The computational fluid dynamics (CFD) numerical simulation and the population balance model (PBM) coupling method were used to simulate the fluid dynamics in the pressurized bubble column with the diameter of 0.3 m and the height of 6.6 m. The results of numerical simulation were compared with the experimental results based on electrical resistance tomography (ERT), and the comparison of the gas holdup distribution and time series diagram of the cross-section collected by ERT in real time was compared with the simulation results. The results showed that the results measured by the electrical resistance tomography techniques were in good agreement with the calculated results of computational fluid dynamics, which could well represent the gas-liquid flow state in the bubble column. It was further demonstrated that ERT technique was feasible for visualization and real-time measurement of gas-liquid two phase flow in the pressurized bubble column.
