Conference Participation: 12th European Combustion Meeting (ECM 2025)

Suraj Prashad Sharma represented our team at ECM 2025: The 12th European Combustion Meeting, held in Edinburgh, Scotland, from 7–10 April 2025 (Conference/Paper Link).

At this international event, Suraj delivered a presentation titled: “Investigating the Long-Term Stability of Air Nanobubbles and Their Impact on Droplet Breakup.”

The research explored the generation, stability, and atomization effects of air nanobubbles (ANBs) in gasoline. ANBs (50–500 nm) were produced using a hydrodynamic cavitation generator and characterized for size, concentration, and zeta potential. Gasoline ANBs demonstrated long-term stability, reaching an initial concentration of 5.12 × 10¹¹ bubbles/mL and stabilizing at approximately 10⁸ bubbles/mL after one week.

Key findings from the study include:

• ANB-enhanced gasoline produced smaller droplets, improved atomization, and more uniform sprays compared to pure gasoline.

• The observed benefits are linked to micro-explosive bubble behavior during injection, which enhances droplet breakup.

• Incorporating nanobubbles into fuel could improve spray performance and potentially increase combustion efficiency.
