An extended model investigation was conducted in a laboratory flume to determine downwind temperature distributions and the recirculation and interference characteristics of buoyant jets (forced plumes) issuing from 1/150-scale models of Marley Class 600 Double-Flow and from Marley round mechanical draft towers. Various tower lengths, stack heights, and stack spacings were tested in order to quantify the recirculation ratio and to delineate temperature contours in the plumes. Increasing stack height and stack spacing both reduce recirculation. Round towers have significantly lower recirculation ratios than rectangular ones.
