Abstract

The studies of laminar natural convection film condensation progress of Freon vapor in the presence of air were made on a horizontal tube. A physical model was presented and numerical solution was obtained by means of an integration technique. Also the simulated experiment was performed to verify the proposed model, and variation laws of calculated values are shown to agree with those of experimental values within the limits of common concentration of air.
