Abstract
Hydraulic model studies at varying Reynolds numbers for a buoyant, rectangular, surface jet entering at right angle to a uniform crossflow of depth equal to the jet discharge channel depth, show a significant decrease in jet penetration into the crossflow as Reynolds number was increased from 2500 to 22,700. Highly buoyant jets having internal Froude numbers ranging between 1 and 1.65 were studied. Shapes of trajectory curves for these jets were found to agree with trajectory laws for buoyancy-dominated flows developed using dimensional arguments, whereby plume penetration into the crossflow varies with distance along the crossflow channel, to the 3/4 power in the nearfield, and to the 2/3 power in the farfield.Keywords
