Evaluation of Mathematical Models for Characterizing Plume Behavior from Cooling Towers. Volume 3. Plume Rise from Mechanical Draft Cooling Towers

摘要

Various methods commonly used to predict the length and height of the visible plume produced by an array of mechanical-draft cooling towers are evaluated by comparing predictions with observational data from the Benning Road Power Station and from a small array of towers at the Purdue University Power Plant. Four different approaches - empirical, integral, cloud-physics, and finite-difference - are examined. Statistical estimates of predictive capability are given. Problems inherent in the application of these approaches are discussed. Observations concerning areas of weakness and thus areas of potential improvement are made.
