The mechanism of cross-flow vacuum membrane distillation (VMD) was discussed in this paper, and the coupled process of heat and mass transfer in numerical simulation was realized by writing user defined function (UDF). The numerical simulation results of membrane flux were well agree with experimental data. The membrane flux in various conditions of feed velocity, feed inlet temperature and vacuum degree was obtained in numerical simulation. Around the cross-section of a single hollow fiber, velocity distribution was approximately symmetrical; TPC and heat transfer coefficient distribution are consistent.
