Experiments on several finite length line sources of heat and momentum in the form of elevated (rows of stacks) and surface (slot) releases were conducted in a water tunnel. Plume behavior was documented through detailed temperature measurements of the plume cross section and by photographing the dyed plume. Results indicate the nature of any plume trajectory and growth enhancement and confirm the empirical relation for the liftoff distance for a buoyant surface plume given by Meroney (1979). In addition to the liftoff distance, the shape of the plume contact zone was measured and related to various regions of plume trajectory and cross-sectional shape. Plume trajectories from elevated line releases are adequately predicted by standard single source formulations; however, plume cross-sectional area is significantly overpredictedRead More
