... layer transition. Also presented is a Particle Imaging Velocimetry (PN) system developed for these experiments and employs seed injection upstream of the channel's flow straightener. Finally, a description is given of instrumentation mounted in the foil for measurement of vibration and surface static...

... This project deals with free-surface wave-induced separation on a NACA0024 foil over a range of conditions, along with the validation of the results from the towing tank. The simulations are performed using CFDSHIP-IOWA (a general purpose research code for ship hydrodynamics) and validated using...

... into the tip vortex or slow capture with a spiral trajectory around the vortex. The results also reveal a scaling problem, analysis of the bubbles shows that while the bubbles in the large-scale foil tests, have a spherical -elliptical shape when they are scaled to cavitation tunnel they are spherical...

... A stationary 3-D free tip hydrofoil was constructed and tested in a water tunnel at the Marine Hydrodynamics Laboratory at the Massachusetts Institute of Technology. The foil had moderate skew and was designed to produce a tip vortex like that typically seen on a modem free tip propeller blade...

... An experimental study to measure developed thrust from a rigid foil subjected to unsteady oscillatory motion was conducted in the towing tank at Memorial University of Newfoundland. The foil tested had a rectangular planform, NACA0019 section, span of 400 mm, and aspect ratio 6...

... Laminate construction technology is used to reduce the local angle of attack at the tip of an elliptic foil to delay the inception of tip vortex cavitation. As the angle of attack is increased on the foil, the increased lift causes the tip to flex in a direction that relieves the hydrodynamic...

... geometry has been found to be sensitive to the panel arrangement at the foil leading edge. Pressure distributions compare very well with linearized analytical results at small angles of attack, but the non-linear effects are noticeable at larger angles of attack. foil convergence taxa-at au-tin...

... This paper presents a method to design foil sections for marine propellers or hydrofoils using inviscid and boundary-layer theory. The current configuration allows a variety of goals and constraints including cavitation inception prediction, lift/drag maximization, and flow separation avoidance...

... A supercavitating hydrofoil experiment is performed at the MIT Variable Pressure water tunnel, at several angles of attack and cavitation numbers. The velocity is measured on a rectangular contour surrounding the foil and cavity, and the results are compared to those from an analysis method...

.... A method for measuring surface pressure in transient cavities was successfully developed and is discussed in the text. In a partial cavity flow the pressure coefficients measured in the wetted region of the foil away from outside the cavity were found to coincide with the pressure measurements in a fully...

... A flexible fin propeller model with a rectangular oscillating foil of aspect ratio 4.0 has been tested in the Hydrodynamics Laboratory of the University of Glasgow. The performance of the model was tested in both forward speed zero speed conditions. Experimental results are compared...
