SUPERCRITICAL FLOW OVER SILLS

Experimental investigations have been carried out to study the supercritical flow has been categorized into two distinct types depending upon the ratio of the sill height to upstream depth and the Froude number. This classification also corresponds to the splashing and nonsplashing conditions. The stagnation, wake, and reattachment pressures have been investigated. The flow conditions have been explored when the downstream face pressures and the bed pressures become negative. An almost constant drag coefficient value, obtained from the present experiments, substantialed the drag characteristics of bluff bodies in open channels. /ASCE/
