CFD Research Corporation (CFDRC) is developing advanced CFD spray/atomization models for the purposes of simulating spray combustion processes in furnaces, boilers and gas turbines. Ongoing development includes:

• Lagrangian spray in 3D unstructured parallel grids
• Incorporation of models for primary atomization, secondary atomization, collision/coalescence, deformation, turbulent dispersion, etc.
• Incorporation of multi-component droplet and dense spray models into the simulation framework
• Incorporation of supercritical and superheated vaporization models
• Incorporation of advanced spray-wall interaction models
• Development of specific atomization models for pressure swirl, airblast, and jet-in-crossflow
• Validation of spray modules against NIST data and other datasets

Multiple projects are focusing on liquid jet-in-gas crossflow atomization modeling. A novel Boundary Layer Stripping (BLS) model has been developed and validated. In addition, a new Eulerian Jet (EJ) model is being implemented in which the liquid core blocks off the gas stream, resulting in improved near-wall spray/atomization predictions. And finally, liquid pulsation, and models to simulate its effect on penetration/atomization, are being developed and validated.
