Increasing the hydrogen substitution ratio significantly reduces unburned hydrocarbons by over 50% from HSR 50 to HSR 90, enhancing emissions profiles.
At HSR 50, stronger breakup from higher Weber number leads to smaller droplets and faster droplet velocities, optimizing spray characteristics.
The hybrid combustion model effectively connects spray dynamics to combustion behavior, demonstrating clear linkages in fuel behavior across HSR levels.
Further advancements in dual-fuel configurations may be guided by findings on HSR influences on combustion phasing and vapor penetration.
