Research Interests

Liquid propellant rocket engine instability driven by combustion transients. Thermo-mechanical principles are used study the response of a gas to spatially distributed, transient heat addition, 听The modeling is based on non-dimensional reactive Navier Stokes equations, enabling the identification of significant non-dimensional parameters

Societal Impact

My rocket engine stability modeling is designed to familiarize the research community with a variety of instabilities not considered in the past and to enable liquid propellant rocket engine designers to be aware of physical processes that can occur to the detriment of performance.
