The stability of the flow past a row of sqtuare bars, which is placed across a uniforrn flow,is investigated nurnerically. Two-dinaensional and incompressible flow field is assumed. It isfound that each jet which flows between the square bars is independent of each other whenthe pitch-to-diameter ratio of the row is large. However the confluence of several jets occurswhen the pitch-to-diameter ratio is srnall. It is fotnnd that the confluence of couples or tripletsof jets is a consequence of a pitchfork bifurcation and the critical Reynolds numbers for thepitchfork bifurcations are evaluated f'or each value of the pitch-to-diameter ratio. An experimentto visualize the flow field is also made and the confluence of' jets is confirmed.
