High-speed visualization and PIV measurements of cavitating flows around a semi-circular leading-edge flat plate and NACA0015 hydrofoil

A. Yu. Kravtsova, +9 more
- 01 Apr 2014 - 
TL;DR: In this paper, a flat plate with semi-circular leading edge and a NACA0015 hydrofoil at attack angles ranging from 0° to 9° and with varying cavitation number were investigated using high-speed imaging visualization (HIV) and particle-imaging velocimetry (PIV).
Journal ArticleDOI

Planar fluorescence for round bubble imaging and its application for the study of an axisymmetric two-phase jet

Yerbol K. Akhmetbekov, +4 more
- 01 Jan 2010 - 
TL;DR: In this paper, a correlation-based processing algorithm for bubble identification by a planar fluorescence for bubble imaging (PFBI) technique is presented, which includes procedures to identify bubble positions and sizes, as well as to track bubbles and correct bubble displacement vectors.
Journal ArticleDOI

Bubble patterns recognition using neural networks: Application to the analysis of a two-phase bubbly jet

Igor Poletaev, +4 more
- 01 May 2020 - 
TL;DR: A novel approach based on neural networks to recognize bubble patterns in images and identify their geometric parameters and results proved that the implemented method increases the identification accuracy, reducing errors of various kinds, and lowers the processing time compared to conventional recognition methods.
Journal ArticleDOI

Control of unsteady partial cavitation and cloud cavitation in marine engineering and hydraulic systems

Ebrahim Kadivar, +7 more
- 21 May 2020 - 
TL;DR: In this article, the authors employed a high-speed imaging method to explore the spatial patterns and time evolutions of cavitation structures and utilized a hydroacoustic pressure transducer to record and analyze local pressure pulsations due to the collapse of the cavities in the hydrofoil wake region.
Journal ArticleDOI

Cavitating flow around a scaled-down model of guide vanes of a high-pressure turbine

Mikhail V. Timoshevskiy, +12 more
- 01 Jan 2016 - 
TL;DR: In this paper, high-speed imaging was used to analyze spatial patterns and time dynamics of the gas-vapor cavities, as well as for evaluating the characteristic integral parameters.
