Plume Rise from Two or More Adjacent Stacks.

摘要

Observations of plumes from two or more stacks show that the plumes frequently merge as they rise. If the resultant plume rises higher than the individual plumes would have separately, the rise is enhanced. This report describes a study, conducted under contract to the State of Maryland's Power Plant Siting Program, that investigates plume rise enhancement. The three major parts of the study were (1) a laboratory study on the interaction of line thermal pairs released in various configurations to determine the dynamics of plume merging, (2) a wind tunnel study of plume rise from one to four stacks to measure plume rise enhancement and (3) an analysis of field data from Tennessee Valley Authority steam plants to determine if plume rise enhancement is observed for actual power plant plumes.
