Non-linear Theory for Partially Cavitating Hydrofoils

Re-entrant Jet Modelling for Partially Cavitating Two-dimensional Hydrofoils

The computational analysis of partial sheet hydrofoil cavitation in two dimensions is performed. Particular attention is given to the method of simulating the flow at the end of the cavity. A fixed-length partially cavitating panel method is used to predict the height of the re-entrant jet, using the values of the cavitation number and the drag coefficient. The jet surface is subsequently const...

An Improved Boundary Element Analysis of Cavitating Three-dimensional Hydrofoils

A theoretical analysis of three–dimensional cavitating flows based on a boundary element approach which includes rotational and viscous flow effects is presented. Partial sheet cavitation is studied by a closed–cavity nonlinear model which includes the prediction of the cavity detachment point. The trailing vorticity path is described by a wake– alignment technique. Viscosity effects are includ...

A multi-fidelity framework for investigating the performance of super-cavitating hydrofoils under uncertain flow conditions

High-speed Imaging and Piv Measurements in Turbulent Cavitating Flows around 2d Hydrofoils

The paper reports on high-speed imaging and PIV study of cavitating flows around a flat plate with semicircular leading edge and a NACA0015 hydrofoil. Both foils were investigated at a series of attack angles ranging from 0 to 9° with varying cavitation number. Several known types of cavitation common to both foils, but also some different patterns, were registered. At small angles of incidence...

Linearized Theory of a Partially Cavitating Plano-Convex Hydrofoil Including the Effects

The linearized treatment of the flow over a partially cavitating single hydrofoil having a flat pressure surface and a circular-arc suction side is presented. The flow is treated as a two-dimensional, steady, inviscid flow. Further assumptions made are those of incompressibility and irrotationality. The results obtained are compared with experiment and generally good correlation is found for th...
