<초록>
In this study, numerical modeling was performed to analyze wet air flow through a coaxial pipe subject to dew condensation for various outer surface temperatures of the inner pipe. The wet air was assumed to be of 20℃ and 80 % RH at constant velocity at inlet and the outer surface of coaxial pipe was considered to be under adiabatic condition. For 4 cases of inner pipe surface temperature ranging from 1℃ to 7℃, the distributions of flow parameters such as temperature, velocity and density were examined and compared. Also condensate mass fraction distributions for each case model were investigated and it was found that for the case of 7℃condition, the condensate mass fraction was about 0.0032 which is 2.4 times smaller than that of 1℃ condition.
