... the hopper system of a 4500 m 3 trailing suction hopper dredger as the research object and applies the Free Surface Model to simulate the water-air two-fluid flow during the overflow process. Aiming at reducing the thickness of the overflow layer and meanwhile decreasing the air entrainment through...

... ABSTRACT The trailing suction hopper dredger(TSHD) completes the sediment loading by the hopper system. The loading efficiency of the hopper system is affected by the hopper geometry. The geometry of hopper should be optimized according to the loading and deposition process in hopper, so...
