- •
Swirl ratio and uniformity index was assessed for six different engine designs.
- •
Lower bowl-depth and higher bowl radius create higher squish and swirl.
- •
The best design for power boost and emission control strategies were identified.
- •
The flow dynamics are considered based on TKE and also the flow field vectors.
