Abstract

The application of the maximum plume rise formula for bent-over industrial plumes to visible cooling tower plumes depends on the validity of two assumptions: the neglect of finite source size and the neglect of condensation effects. These produce errors which, in many cases, tend to compensate. The effect of finite source size is examined analytically and an alternative formula for maximum plume rise is derived.
