- Abstract
A 3D mathematical model to the condensation of pure vapor flowing downward in an inclined flat finned tube is proposed and implemented numerically in Wolfram Mathematica®. The predicted values for condensate rate and mean condensation HTC(Heat Transfer Coefficient) are in good agreement with the experimental data from a prototype tube(length: 2600 mm, altitude: 50mm,width: 3 mm, incline angel: 60°). The deviation is less than 15 %. Using the numerical model to calculate the local film thickness and local condensation HTC on the tube plate, it is found that the gravity makes dominant effect on processes of the condensation.
