Cavitation bubbles dynamics and cavitation erosion in water jet
Results in Physics, 2018 A water jet test rig is used to the cavitation test of the brass samples. The single crater and the pits-group, are found on the specimen surfaces after 15 h test. A water jet cavitation model with the sound interaction among bubbles, is developed by applying a water pressure of water jet flow fields into the Keller-Miksis equation, so as to obtain the

Cavitation induction by projectile impacting on a water jet [PDF]
International Journal of Multiphase Flow, 2019 The present paper focuses on the simulation of the high-velocity impact of a projectile impacting on a water-jet, causing the onset, development and collapse of cavitation. The simulation of the fluid motion is carried out using an explicit, compressible, density-based solver developed by the authors using the OpenFOAM library.

Analysis of the Formation Mechanism of Secondary Tip Leakage Vortex (S-TLV) in an Axial Flow Pump
Machines, 2022 Studies on the tip leakage vortex (TLV) are extensive, while studies on the secondary tip leakage vortex (S-TLV) are rare. To advance the understanding of the formation mechanism of the S-TLV, turbulent cavitating flows were numerically investigated ...

Study and analysis of the cavitating and non-cavitating jets - Part one: Parameters controlling force, power and the jet behavior [PDF]
Thermal Science, 2020 This paper presents the dependency of the jet power and the cavitation intensity on the working conditions of the cavitating and non-cavitating jet flow. This dependency is indicated by the cavitation erosion process and flow structure. The effects of working conditions on the cavitation erosion were experimentally investigated.

Thoracic Computed Tomographic Characteristics of Canine Blastomycosis
Veterinary Radiology &Ultrasound, Volume 67, Issue 3, May 2026.ABSTRACT While thoracic radiographic studies have described the broad thoracic findings of canine blastomycosis, thoracic computed tomographic (CT) findings have been minimally reported. This single‐center, retrospective, descriptive case series study aimed to characterize thoracic CT features of canine blastomycosis.

Study of unsteady cavitation on NACA66 hydrofoil using dynamic cubic nonlinear subgrid-scale model
Advances in Mechanical Engineering, 2015 In this article, we describe the use of a new dynamic cubic nonlinear model, a new nonlinear subgrid-scale model, for simulating the cavitating flow around an NACA66 series hydrofoil. For comparison, the dynamic Smagorinsky model is also used.
