EXPERIMENTAL STUDY ON TWO LAYER STRATIFIED FLOW OVER HUMP

Abstract

Internal hydraulic jump occured at back of submerged hump disturb stability of two layer stratifiedflow and may influence condition of water enviroiunent substantially. In this paper we oberveprofliles of interfaces in laboratory, and show that compound Froude number, which consist of hyraulic feasures in each layer, and the lower layer thickness at control section appeared atthe downstream of hump are important parameters to control the interface stability and diseussthe relation between these parametes.
