The Effects of Bubble Discharge Depth on the Spreading Radius of Dense Surface Horizontal Jet by Bubble Plume Impinging on the Free Surface

Key Points

• The aim is to investigate the relationship between bubble discharge depth and the spreading radius of a horizontal jet created by bubble plumes.
• Analyzed data from both indoor experiments and field observations to enhance previous findings.
• Systematically varied bubble discharge depth while assessing its impact on jet spreading radius.
• Developed empirical formulas concerning the interaction of density stratification and bubble buoyancy.
• Observed that the spreading radius increases with bubble discharge depth up to a certain point.
• Noted that beyond a specific depth, the spreading radius tends to decrease.
• Findings align with existing empirical formulas related to length scales and stratification.
