Study on Free-Surface-Pressurized-Flow of Pressure Spillway Tunnel under Different Submerged Depth

Abstract:

The free-surface-pressurized-flow is a complicated water-air two phase flow in the spillway tunnel, which should be studied in the engineering practice. This flow pattern existed from open flow to pressure flow with the submerged depth increasing, which has obvious pulsing pressure. The flow transformation and pressure distributions were observed and studied in this paper.
