Sound signature of propeller tip vortex cavitation

Journal of Physics: Conference Series, 2015
The design of an efficient propeller is limited by the harmful effects of cavitation. The insuffcient understanding of the role of vortex cavitation in noise and vibration reduces the maximum effciency by a necessary safety margin. The aim in the present study is to directly relate propeller cavitation sound to tip vortex cavity dynamics.

Effect of Cell Disruption and Protein Extraction on the Structural and Technological Properties of Tetradesmus obliquus Protein‐Rich Extracts

Sustainable Food Proteins, Volume 4, Issue 2, June 2026.
Despite its considerable potential as a functional food ingredient, T. obliquus faces a major limitation in protein recovery due to the rigidity of its cell wall. In the microalgae industry, protein extraction typically involves two main steps: cell disruption and protein extraction.

Image Restoration Algorithm and Propagation Mechanism of Partial Discharge Streamer in Oil–Pressboard Insulation Needle–Plate Electrode

High Voltage, Volume 11, Issue 3, Page 784-796, June 2026.
ABSTRACT Oil–pressboard system is the main insulation form of oil‐immersed transformers, which is prone to partial discharge (PD) and subsequent faults due to contamination or moisture ingress. To investigate the evolutionary characteristics of PD streamers under varying voltages and insulation dimensions, streamer images were captured using a high ...

Numerical investigation of tip leakage vortex cavitation

IOP Conference Series: Earth and Environmental Science, 2019
Tip leakage vortex cavitation is a concern for axial hydraulic turbines. Generally, cavitation may occur in the core of the TLV, often leading to erosion of the runner blades and the casing. The objective of this paper is to study the effects of this phenomenon on the hydrodynamics characteristics of a standard NACA0009 blade.

A Subvoxel Correction of Boiling‐Induced Susceptibility Artifacts in Magnetic Resonance Thermometry and Dosimetry for Monitoring Microwave Thermoablation: A Feasibility Study in a Swine Model

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1698-1713, March 2026.
ABSTRACT Purpose Real‐time monitoring of microwave liver ablation (MWA) using MRI thermometry can be hindered by boiling‐induced susceptibility artifacts. These artifacts cause large temperature measurement errors that prevent accurate lesion size prediction.

An empirical approach for propeller tip vortex cavitation noise [PDF]

, 2018
In this study, the TVI (Tip Vortex Index) technique has been applied to a marine propeller to predict the noise due to tip vortex cavitation. The benchmark DTMB4119 model propeller has been chosen for the hydroacoustic performance analysis in open water condition.
