SUPERCRITICAL FLOW IN RECTANGULAR EXPANSIONS

Experimental study of the validity of the assumptions made by Bagge and Herbich in the analysis of supercritical flow passing through a rectangular expansion. An experimental model was constructed in the laboratory and the resultant surface profiles obtained were compared to those predicted by the mathematical model. Results indicated that the assumptions of frictionless flow and negligible velocity perpendicular to the bed of the channel were too important to be neglected.
