Abstract

Condensation rates and pressure drops are determined for horizontal cross flow of steam in small tube bundles. Steam pressures in the range of 0.2 to 0.8 bar, vapour approach velocities of up to 40 m/s and cooling water velocities in the range of 1.1 to 1.8 m/s are investigated.
The cooling water flow rate and temperature rise are measured for each tube enabling individual as well as overall heat transfer coefficients to be determined. The results are discussed in terms of the vapour flow patterns and the factors which influence condensation such as vapour and cooling water velocity.
Correlations for the condensing heat transfer for both the 1st row and tube bundle are obtained as functions of the important vapour and cooling water variables and it is suggested that such correlations might prove useful in the early design stages of small condensers.
