Plume recirculation and interference in mechanical draft cooling towers

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