Observational analysis reveals significant influences of mass flow ratios on spray characteristics, suggesting important dynamics in fuel injector performance.
Key Points
Interactions significantly altered spray angle and droplet velocity, with the inner swirler's influence stronger at lower fuel rates.
At lower fuel mass rates (2.0 kg/h), the influence of the inner swirler on spray characteristics was pronounced.
Systematic investigation using laser-based diagnostics like PIV and PDPA identified key dynamics in atomization processes.
Findings highlight the collision-coalescence dynamics affecting droplet sizes and velocities, particularly at higher mass flow rates.
