ON TWO-PHASE PRESSURIZED AND UNPRESSURIZED FLOW: BEHAVIOUR NEAR DEPOSITION POINTS

SUMMARY This paper deals with two-phase pressurized turbulent flow and in so doing attempts to bring together on common ground the various disparate approaches to the problem. In particular it is shown that the approach of two-phase unpressurized flow in open channels can be used for pressurized flow also. As a consequence of experimental work in pipes a recommendation is made concerning the point of best efficiency for a pumping system.
