Variable Aspect Ratio Design:

• The invention introduces a swirler with a varying aspect ratio from entry to exit, allowing control over axial, tangential, and crucially, radial velocity components, enhancing fuel-air mixing.

Sheet Cutter:

• The design incorporates sheet breakers at the swirler exit, disrupting liquid sheets into ligaments and droplets, facilitating finer atomization even at lower injection pressures.

Improved Flow Guidance:

• The swirler’s smooth nozzle shape with a variable flow area guides the flow effectively, resulting in higher exit velocity components, contributing to enhanced combustion efficiency.

Enhanced Spray Characteristics:

• Flexibility to adapt trust computation to specific security requirements.

Adaptability in Design:

• The invention allows for flexibility in implementing the variable aspect ratio design on either the hub or tip side of the swirler, providing versatility to suit specific combustor requirements.
