The steady flow due to a non uniform source in an otherwise uniform stream is studied, the source taking the form of an upstream - pointing and a downstream - pointing slender jet, or sheet - jet. The planar - model setting is described, along with applications, and then viscous flow computations are presented. The results show that the sheet - jet source together with the entrainment into the jets upstream and downstream induce an almost sink - like response in the overall flow, in contrast with the effects of a uniform source. The response yields a small eddy at the higher Reynolds numbers of the computations and suggests that large - scale eddies may occur for increased Reynolds numbers ; yet the uniform - source model predicts the upstream stagnation point and some other features well.
