Sheet cavitation inception can be influenced by laminar boundary layer flow separation under Reynolds numbers regimes with transitional flow. The lack of accurate prediction may lead to massive over-prediction sheet certain circumstances, including model scale hydrofoils and marine propellers operating at relatively low number. For non-cavitating flows, the local correlation based transition mo...

In this work, we experimentally investigated the cavitation effects on hydrodynamic behavior of a circular cylinder at different cavitating flows. We analyzed dynamics behind using high-speed camera and also measured associated forces load cell. studied around various types regimes such as cloud cavitation, partial inception. addition, three Reynolds numbers: 1 × 105, 1.25 105 1.5 105. The resu...

Flow inside a rectangular shape nozzle is simulated in this study. Finite volume scheme utilized as the main solver for current Second order to discretize pressure. upwind solving momentum equation. Then equation coupled with continuity obtain pressure and velocity at each cell. Cavitation inception super cavitation also found discussed study results were verified previous Winklhofer et al. exp...

In this paper, the inception of tip vortex cavitation in weak water has been predicted using a numerical simulation, and new scaling concept with variable exponent also suggested for index. The simulations cavitating flows over an elliptic planform hydrofoil were performed by RANS approach Eulerian model. To ensure accuracy present simulations, effects turbulence model grid resolution on invest...
