EXPERIMENTAL INVESTIGATION INTO FACTORS AFFECTING THE TRANSIENT FLOW OF FLUID THROUGH AN ORIFICE IN REALISTIC CONDITIONS

During operations, damage can occur with a resulting ingress or egress of fluid. The incoming water affects the reserve buoyancy and it also change stability hull girder loading. flooding event is vital that flow through damaged orifice movement floodwater around structure be predicted quickly to avoid further ensure environmental safety. empirical measure coefficient discharge used as simplified method quantify rate. In many internal applications estimated 0.6 but recent research shows vary considerably when applied transient flows. This paper uses an experimental setup investigate how changes edges position within affect flow. It then in more realistic scenario, static compartment waves.
