Turbulent flow with small relative submergence

1991
The turbulent structure of flow with small relative submergence, which should be clarified for advanced study of sediment transport in mountain rivers, is different from that with sufficient relative submergence which is familiar to us according to the recent development of research of turbulent open channel flow. In this study, in order to clarify and

Scour and flow around submerged structures

Proceedings of the Institution of Civil Engineers - Water Management, 2014
The results of an experimental investigation on scour of non-cohesive uniform and non-uniform sediment beds and flow around fully submerged structures over a fixed plane bed are discussed. In the study, the submergence factor, Froude number and cylinder Reynolds number for all the experiments were kept in the ranges of 0·25–0·75, 0·23–0·70 and 13 500 ...

Free surface flows over submerged obstructions. [PDF]

, 2015
Steady and unsteady two-dimensional free surface flows subjected to one or multiple disturbances are considered. Flow configurations involving either a single fluid or two layers of fluid of different but constant densities, are examined. Both the effects of gravity and surface tension are included. Fully nonlinear boundary integral equation techniques

Flow regimes of submerged gas jets

2010
The behaviour of a gas jet injected into a liquid has been studied as a function of gas and liquid densities, gas flow rate, tuyere diameter and tuyere design. A novel technique has been developed to study the interaction of a submerged gas jet into injected opaque liquids. The jet is blown through a "half-tuyere" fastened to the plexiglas side wall of

Comparison of Flow Boundary Effects on Critical Submergence of an Intake

2009
In this study, the effects of canal bottom and dead-end wall on the critical submergence of a single rectangular or circular intake are investigated and compared. In order to find the functional relationship involving the critical submergence and the influencing dimensionless variables, dimensional analysis is utilized.
