A SIMPLE NUMERICAL MODELING FOR BEHAVIOR OF FLEXIBLE CURTAIN STRUCTURE CONSIDERING INTERACTION WITH FLOW FIELD

Abstract

  A time dependent 2DV numerical model for behavior of flexible curtain structure was proposed, which is composed of two-way coupling of fluid flow calculation by SMAC method and catenary model of curtain structure. The curtain structure is described as a chain of tracers traveling on flow field creating restoring force which is taken into account for flow field calculation. Trials of numerical applicability were made on behavior of curtain structure in uniform flow and sediment dumping driven flow.
