The separation of gas-steam mixtures by condensation in a vertical tube at high Reynolds numbers

Heat and mass transfer for condensation from a gas-vapor mixture with very high Reynolds numbers was analyzed on a theoretical and experimental basis. A mixture of monofluorotrichloromethane and nitrogen was cooled in a vertical brass tube. The gas concentrations and the Reynolds numbers were in the ranges x sub G between 0.01 and 0.42 and Re between 70,000 and 450,000. The Reynolds number of the condensate film flow reached values of above 1000. A mathematical method was developed to show the various values as a function of the main parameters, such as gas concentration, Reynolds number of the mixture, and cooling length.
