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.
