Abstract
We formulate a general semi-analytical model for multiple tandem jet interaction in a crossflow. For an array of buoyant jets arranging in tandem, the rear jets experience a reduced effective crossflow velocity due to the blockage and sheltering effect of the leading jet. The jet entrainment is modelled by a distribution of point sinks, and the blockage and sheltering effect is modelled by a distribution of doublets-both along the jet axis. The reduction of rear jet effective velocity as observed in previous experiments is successfully predicted by the model.
