Numerical investigation of the aerodynamic breakup of Diesel and heavy fuel oil droplets

- Experimental validation and comparison of aerodynamic breakup between Diesel and HFO droplets.
- Examination of representative engine conditions (We, Oh, Re and ε).
- Rate of deformation, liquid surface area and drag coefficient decrease with Oh.
- Increasing the density ratio, may result in changing the breakup mode.
- Proposed correction factors based on Oh and ε for the breakup initiation time.
