چکیده
The influence of a bulb runner blade hydrofoil shape on flow characteristics around the was studied. Experimental work performed turbine measuring station and single in cavitating tunnel. In cavitation tunnel, visualization hydrofoil’s suction side. Cavitation structures were observed for several numbers. less intense modified than original hydrofoil, delaying onset by tenths number. results tunnel show that modifying existing design parameters played key role reducing inception development, as well size structures. A regression model produced cloud length. length is dependent Reynolds’s number coefficients determination both hydrofoils reasonably high, with R2 values above 0.95. also confirm exhibits improved properties.

Observations of Cavitation on a Three-dimensional Oscillating Hydrofoil
A test apparatus was designed and constructed to observe the effect of sinusoidal pitching oscillations on the cavitation of thredimensional hydrofoils. The apparatus is capable of oscillating hydrofoils at a rate up to 50 Hz and provides for adjustments in oscillation amplitude and mean angle of attack. Observations of the effect of pitching oscillation on cavitation have been made for a NACA ...
متن کاملLES of Partial Cavitation Around a 2D Plane-Convex Hydrofoil Large Eddy Simulation of Partial Cavitation Around a 2D Plane-Convex Hydrofoil
Investigations of attached partial cavitation are important because to prevent damages in hydrulic machinery and to reduce the costs. As expected computational fluid dynamics (CFD) methods have been developed for more than 40 years to understand this phenomenon and to improve the machinery designs, as pumps and hydraulic turbines. However, cavitation appears at high Reynolds numbers, so that, t...
متن کاملEvaluation of turbulence models for the numerical prediction of transient cavitation around a hydrofoil
The objective of this paper is to evaluate the predictive capability of three turbulence models for the simulation of unsteady cavitating flows around a 2D Clark-y hydrofoil. Three turbulence models were standard k-ε model, hybrid model of density correction model (DCM) and filter-based model (FBM) and an improved partially-averaged Navier-Stokes model (PANS) based on k-ε model. Using the above...
متن کاملExperimental investigation of added mass effects on a hydrofoil under cavitation conditions
The influence of leading edge sheet cavitation and supercavitation on the added mass effects experienced by a 2-D NACA0009 truncated hydrofoil has been experimentally investigated in a hydrodynamic tunnel. A non-intrusive excitation and measuring system based on piezoelectric patches mounted on the hydrofoil surface was used to determine the natural frequencies of the fluid–structure system. Th...
متن کاملOn the Dynamics and Acoustics of Cloud Cavitation on an Oscillating Hydrofoil
Observations have been made of the growth and collapse of surface and cloud cavitation on a finite aspect ratio hydrofoil oscillating in pitch. The cavitation was recorded using both still and high-speed motion picture photography, and the variations with cavitation number and reduced frequency of oscillation were investigated. The noise generated by the cavity collapse was also measured and an...
