Research Areas
Experiments , diagnostic development and phenomenological modeling of the fluid dynamics and thermodynamics associated with reciprocating engines:
• Spray and liquid film diagnostics and diagnostic development
• Shear driven film motion and breakup
• Thermodynamic engine modeling (multi-cycle dynamics and control models)
• Engine combustion sensing (pressure, vibration)
• “Problem solving” – Emissions, noise, fuel systems and flexibility, etc.
Experimental Facilities
• Imaging
• Spray drop size and velocity
• Spray gas phase specie concentration
• Liquid film thickness
