Abstract: This paper studies the ability of a Shock-Fitting approach in computing air pocket entrapments in a closed conduit transient flow, caused by suddenly blocking the downstream end. The flow is pressurized at the upstream, ...

Abstract: This paper proposes a modification to a previous shock tracking–capturing approach used for simulating transient flows in stormwater systems. Based on the Godunov-type finite-volume (FV) method, this modified approach uses ...

Abstract: The emptying process of initially stagnant full-pipe flows in sewer systems and water transmission lines was extensively studied in the literature. The following air intrusion and depressurization wavefronts can cause ...

Abstract: The gravity flow in sewer systems may change to partially pressurized flow for reasons including rapid filling, and maintenance and repair. During this alteration, air can be entrapped and becomes highly pressurized, and ...
