Experimental Investigation into the Effects of Cross Flow with Condensation of Steam and Steam-Gas Mixtures on a Vertical Tube

Abstract

As part of a programme of comparison of filmwise and dropwise condensation of steam, it was required to know the effect of a cross flow of steam, with some non-condensable gas present, over the condenser tube. A 'steam tunnel' was developed in order to produce the required steam velocity with a limited steam supply at atmospheric pressure. Details of the apparatus are given together with the results of tests on a vertical tube.
