Abstract

This paper is a review article and considers the influence of wake chopping on the size distribution of water droplets formed by homogeneous nucleation in steam turbines. The studies by several investigators are summarized. All the studies show that the fluctuations caused by the wakes can broaden the size distributions of the nucleated droplets substantially and account for the polydisperse nature of the droplet distributions and coarse water observed in turbines. The effect of the presence of impurities in steam on its nucleation behaviour is also discussed.
