文摘
- •
Small spray angles cause delayed fuel ignition, which increases species emissions.
- •
Moderate swirl numbers reduce species emissions and increase the heating output.
- •
Large swirl numbers or spray angles speed up fuel ignition but shorten the flames.
- •
Excessive flame shortening reduces species emissions but also the heating output.
