摘要：

Two-dimensional gas-liquid direct-contact heat-mass transfer in vertical pipe of CWS entrained-flow gasifier was simulated using VOF multiphase flow model. Water vapor diffusion in the syngas, surface tension and radiation heat transfer were considered when establishing the mathematics model. The corresponding experiment was conducted to validate the simulation results, and the numerical prediction of the temperature distribution was in a good agreement with experiment. With this model, the vapor concentration and the flow pattern of the falling water film with or without phase change were predicted.
