#Title: Study on the Correlation Between Air Content and the Inception Characteristics of Vortex Cavitation | SNAK Autumn Conference 2025Title: Study on the Correlation Between Air Content and the Inception Characteristics of Vortex Cavitation | SNAK Autumn Conference 2025.

#Description:
This video features my technical presentation delivered at the SNAK Autumn Conference 2025 held at CECO (Changwon Exhibition Convention Center). The talk presents new experimental findings on how dissolved oxygen (DO) content influences the inception and desinence behavior of vortex cavitation on a NACA 16-020 hydrofoil under controlled cavitation tunnel conditions.

🔬 Key Highlights of the Presentation:

1. How dissolved oxygen (4–10 ppm) modifies cavitation susceptibility.

2. Differences between vortex cavitation (VC) and tip vortex cavitation (TVC).

3. DO-dependent changes in inception/desinence cavitation number.

4. Angle-of-attack effects on DO sensitivity.

5. Bubble nuclei dynamics and vortex-core pressure physics.

#Experimental setup: cavitation tunnel, high-speed video analysis, DO measurement techniques.

Implications for naval hydrodynamics, noise control, and hydrofoil design.

🎯 Objective:
To establish a quantitative correlation between air nuclei content and vortex cavitation inception, providing new physical insight into vortex-core bubble dynamics and hysteresis behavior.
