RAVELET, Florent; BAKIR, Farid (2011)
We study the pressure drop and flow regimes for large spheres with respect to the diameter of the pipe (5, 10 and 15%) by differential pressure measurements and visualizations. Two densities are used. The losses are smaller ... -

In centrifugal and axial pumps, the flow is characterized by a turbulent and complex behavior and also by physical mechanisms such as cavitation and pressure fluctuations that are mainly due to the strong interactions ...

The unsteady character of the sheet cavity dynamics on the suction side of hydrofoils, on convergent–divergent nozzles or on blades in turbines and propellers is responsible for many issues like erosion, noise and vibrations. ...

An experimental study on counter-rotating axial-flow fans was carried out. The fans of diameter D = 375 mm were designed using an inverse method. The counter-rotating fans operate in a ducted-flow configuration and the ...

Due to high requirements of energy consumption level, weight and dimension restriction in many industrial fields, compact axial turbomachines are expected. Counter-rotating axial-flow fans may be a solution. The design and ...

A prototype device for measuring the volumetric flow-rate by counting vortices has been designed and realized. It consists of a square-section pipe in which are placed a two-dimensional bluff body and a strain gauge force ...

This article presents an experimental study of the hydraulic transport of very large solid particles (above 5 mm) in an horizontal pipe. Two specific masses are used for the solids. The solids are spheres that are large ...
