The calculation method of the local heat transfer coefficient of forced convective evaporation under annular flow pattern of non-azeotropic mixed medium in horizontal tube was deduced. The calculation formula of the local heat transfer coefficient was deduced. The influence of evaporation heat transfer The main factor. The predicted results obtained by the formula in this paper are compared with the experimental data and the results are consistent
