Unsteady air–water flow measurements in sudden open channel flows
Measurements of air–water flow properties are reasonably simple in steady flows, but not so in unsteady flows. Some studies investigated periodic flows in which instantaneous data were averaged over several cycles. During the present work, new unsteady air–water flow measurements were performed in sudden open channel flow surges. Unsteady air–water flow measurements were performed in the wave f...
متن کاملTranscellular Water Flow Modulates Water Channel Exocytosis
Introduction The regulation of osmotic water permeability (Pf) by vasopressin (VP) in kidney collecting tubule involves the exocytic-endocytic trafficking of vesicles containing water channels between an intracellular compartment and apical plasma membrane. To examine effects of transcellular water flow on vesicle movement, Pf was measured with 1-s time resolution in the isolated perfused rabbi...
متن کاملDecentralised Pi Control of an Open Water Channel
In this paper we consider decentralised PI control of the water levels in an irrigation channel. The water levels are controlled using overshot gates located along the channel, and the output of the controllers is the head over gate. This choice of manipulated variable is advantageous since the head over gate is directly related to the flow over the gate. The PI controllers are augmented with a...
متن کاملImpact of the Confluence Angle on Flow Field and Flowmeter Accuracy in Open Channel Junctions
Open channel junction is one of the most common hydraulic structures that are used in various practical situations such as sewer, drainage, and flood control systems. Knowing the fluid flow behavior, is one of the most important topics in designing the efficient open channel junctions. The complexity and deviation of flow in the junction’s zone disrupts the proper functioning of the flowmeter d...
متن کاملShape Effects and Definition of Hydraulic Radius in Manning 's Equation in Open Channel Flow
In the Manning equation the hydraulic radius can be defined as the cross-section dimension of the shape. In pipe flow the bed shear stress is assumed to be uniformly distributed along the wetted perimeter which cannot be true in open channel flow. Hence, three approximation of the true boundary shear-stress distribution are examined and more practical conveyance depth or resistance radius formu...
