A Study of the conditions of non- sedimentation in Karkhe Inverted Siphon by using a Laboratory Model
Deposition of sediment inside the conduit structures reduces the flow cross section area and increases the flow roughness which causes reduction of flow discharge passing through the conduit. Among the methods which can prevent sediment deposition is non sedimentation condition in the structure, Since the critical section of the inverted siphon in sedimentation is the outlet. In the begining of...
متن کاملInvestigating the effect of flow entrance and existence of baffle on sedimentation efficiency using Discrete Phase Model (DPM)
Presence of salts in water has been one of the biggest problems of industrial equipment such as evaporators, boilers, and pipes. These salts gradually form scales on evaporators and boilers tubes and reduce their efficiency. Pretreatment processes are conducted to remove these salts; with sedimentation tanks being one of the essential equipment used in these processes. This study numerically si...
متن کاملHigh Reynolds Viscous Flow Simulation Past the Elliptical Airfoil by Random Vortex Blob
In this paper, numerical simulation for a two-dimensional viscous and incompressible flow past the elliptical airfoil is presented by Random Vortex Blob (RVB). RVB is a numerical technique to solve the incompressible, two-dimensional and unsteady Navier-Stocks equations by converting them to rotational non-primitive formulations. In this method, the velocity vector at a certain point can be cal...
متن کاملComputational fluid dynamics simulation of the flow patterns and performance of conventional and dual-cone gas-particle cyclones
One of the main concerns of researchers is the separation of suspended particles in a fluid. Accordingly, the current study numerically investigated the effects of a conical section on the flow pattern of a Stairmand cyclone by simulating single-cone and dual-cone cyclones. A turbulence model was used to analyze incompressible gas-particle flow in the cyclone models, and the Eulerian–Lagrangian...
متن کاملEvaluation of Energy Dissipation and Flow Rate of Elliptical-Lopac Gate under Sudden Transition Condition
Lopac gates, with the benefits of easy installation, automation and the ability to pass sediments and floating objects, are among the new structures considered for water level regulation and flow control in the irrigation canals. Converting the shape of the gate from a rectangular one to an elliptical one allows the flow rate to be increased by the same water level. In the present study, the ef...
