abstract

To enhance the practicality of the separate type heat tube in large-scale industrial application, the authors have adopted a non-vacuum separate type heat tube in which quantitatively predicting condensation heat transfer of vapor in the presence of stagnant high partial pressure non-condensable (NC) gases is vital to the task of design. So the condensation heat transfer in a V-shape tube with high partial pressure non-condensable gases was simulated based on a 3D steady state VOF model coupled with the MS (Maxwell-Stefan) equation for considering the effect of stagnant high partial pressure non-condensable gases on condensation heat transfer. The results show that the high partial pressure non-condensable gases have a limited influence on the condensation heat transfer, and they are constrained in a narrow space at the rear of the tube due to the forced convective vapor, therefore, a small part of the pipe wall has lower local heat flux and condensation heat transfer coefficient, while most part of pipe wall has higher performance of condensation heat transfer. The calculated results are in agreement with the experimental data.
