Abstract
An investigation of continuous dense gas plumes released from a surfac e area source and dispersing downwind solid obstacles is presented. Co mparison with passive plumes released in the same experimental conditi ons enables us to emphasize the buoyancy effects. Some quantitative st atistical results such as mean concentration, root-mean-square fluctua tions, skewness and kurtosis an given. The experimental technique used , visualizations and digital image processing, allows us to characteri ze the geometrical evolution of the plumes. (C) 1998 Elsevier Science B.V.
