Interaction between dry granular flow and deflectors
The application of seawall deflectors for reflecting inviscid waves into the sea have been well established. Recently, rigid barrier deflectors have been proposed prescriptively for mitigating geophysical landslides, but flow characteristics differ fundamentally from waves and merit investigation. In this study, flume tests were used to calibrate a discrete element model to explore the interact...
متن کاملSimulation of local scour caused by submerged horizontal jets with Flow-3D numerical model
One of the most concerning issues for researchers is to predict the shape and dimensions of the scour pit nearhydraulic structures such as the base of bridges, weirs, valves and stilling basins due to both financial and humanhazards induced by destruction of the structure. As the scour issue has its own complexity in relation to themultiplicity of effecting factors on it, in this study therefor...
متن کاملNumerical solution of unsteady flow on airfoils with vibrating local flexible membrane
Unsteady flow separation on the airfoils with local flexible membrane (LFM) has been investigated in transient and laminar flows by the finite volume element method. A unique feature of the present method compared with the common computational fluid dynamic softwares, especially ANSYS CFX, is the modification using the physical influence scheme in convection fluxes at cell surfaces. In contr...

متن کاملAerodynamic Performance of Fan-Flow Deflectors for Jet-Noise Reduction
This paper presents a computational study on the aerodynamic effectiveness of vane-type fan-flow deflectors used for reducing jet noise from a supersonic turbofan exhaust with bypass ratio of 2.7. The numerical code solved the three-dimensional Reynolds-averaged Navier–Stokes equations. A series of nozzle configurations using deflector vanes of variable number, airfoil section, azimuthal mounti...
