A numerical model of forced convection condensation on a horizontal tube in the presence of noncondensables

This paper presents the results of validation a model in which the flow of a vapour—air mixture is described by the Navier–Stokes equations for laminar regime or by the RANS equations for turbulent regime and the condensate film is considered using a one-dimensional model. The data available from the literature was employed to verify the proposed model for forced convection condensation with and without noncondensables. The numerical results are in good agreement with the literature experimental data. A description is presented of the details of the numerical implementation of the algorithm developed. The results of the addition test to validate the assumptions and simplifications used in the model are also presented.
