The use of the Reynolds flux model for predicting static pressure gradients in the flow of a condensing fluid is explained. Experimental results for steam condensing in a horizontal straight tube are presented and compared with the theoretical analysis.
Studies have been made of the flow patterns around porous cylinders with mass extraction at the surfaces. These studies help to explain the behaviour of saturated steam flowing over banks of cooled tubes in surface condensers.
An aerodynamic analogue using porous cylinders has been used to examine the necessity of having access lanes in steam condensers.
