The present study deals with the shedding process of the Kármán vortices at the trailing edge of a 2D hydrofoil at high Reynolds numbers. Investigations are performed in order to evaluate the ability of an unsteady numerical simulation to accurately reprod ...
The study of turbulent flows has always been a challenge for scientists. Turbulent flows are common in nature and have an important role in several geophysical processes related to a variety of phenomena such as river morphology, landscape modeling, atmosp ...
This study investigates the modifications of the turbulent boundary layer that develops on the suction side of a NACA0015 hydrofoil when a stable partial cavity takes place near the leading edge of the foil. The velocity field measured in non cavitating co ...
The typology of the underground waters of the flyschs of the Niesen and Gurnigel tectonic nappes form part of the AQUITYP project which has been worked on by the geology laboratory of the Swiss Federal Institute of Technology in Lausanne since 1981. Its pr ...
This work presents an analytical investigation of two-phase pressure drops during evaporation in horizontal tubes. Based on a comprehensive state-of-the-art review and comparison with two-phase frictional pressure drop prediction methods, it is proven that ...
This paper presents investigations of unsteady flow conditions influence over cavitation dynamics. Measurements of wall pressure fluctuations in a model turbine are first introduced. It is shown that the wake of the spiral casing tongue modulates cavity dy ...
