Abstract
Flow patterns upstream and downstream of a sudden-contraction cross-section in a vertical straight pipe were presented. By comparing with flow pattern s in uniform cross-section vertical tubes, the effect of the sudden change in pipe diameter on flow patterns was analysed. Flow pattern transition mec hanisms were discussed and transition criteria for flow pattern transitions were deduced accordingly using the dimensional analysis.
