Abstract: Subcritical flow in a short expansion tends to become detached from its sidewalls and create turbulent eddies. This phenomenon can cause undesirable losses of flow energy and channel erosion. This paper numerically ...

Abstract: Irrigation channels need expansions to provide a cross-sectional transition. Expansions often cause flow separation, turbulent eddy motions, channel erosion, and flow energy dissipation. The purpose of this paper is to ...

Abstract: Irrigation networks use a warped transition to connect a narrow rectangular channel section with a relatively wide trapezoidal earth-channel section. The flow through the transition often separates from its sidewalls. This ...

Abstract: Irrigation and water-supply systems commonly need channel transitions to provide changes of channel section. Warped transition (WT) is an option for transitioning from a narrow rectangular channel to a wide trapezoidal ...
