Some Comments on Cavitating Flow Simulations in Venturi and Hydrofoil Geometries

Résumé

Since the first studies published by [1,2], many numerical and physical models have been applied to simulate and analyze cavitating flow simulations in simple geometries (as hydrofoils, injectors or Venturi devices, for example), as well as in more complex geometries of hydraulic machines (pumps and turbines). Throughout these 30 years, the LEGI laboratory (Laboratoire des Ecoulements Géophysiques et Industriels) has actively participated in several research works applying different approaches and geometries. Homogeneous [3-6] and two-phase flow models [7] have been developed and evaluated for several turbulent cavitating flows, taking into account thermodynamic effects or not. This paper presents a synthesis of the most important results obtained in the laboratory on Venturi and hydrofoils configurations for cold water. It also describes the problems encountered, lessons learned and experiences acquired. The review highlights some conclusions on the influence of cavitation, turbulence and numerical models on the prediction of unsteady behavior of cavitating flows.
