THEORY OF VAPOR CONDENSATION IN THE PRESENCE OF NON-CONDENSING GASES,

Abstract

The aim of the paper is a consideration of the condensation of a vapor diluted with non-condensing gases, with strict account of the basic diffusion process, but without account of the secondary factors of external heat transfer. For this we will assume the heat transfer of the surrounding medium from the wall to be so intensive that the temperature of the surface on which the condensation occurs, i.e., the internal surface of the film of condensate, can be assumed constant and equal to the given temperature of the surrounding medium. With these assumptions, the Stefan equation can be integrated analytically over the whole length of the apparatus; a simple and convenient equation is obtained, which shows graphically the basic qualitative regularities of the process and permits making rough calculations with exceeding ease and simplicity without unwieldy and laborious graphical methods.
