Unique Dynamics of Reacting Systems Under Near Limit Conditions
July 21 @ 2:00 pm - 3:00 pm
Speaker: Prof. Tanvir Farouk
Professor, Department of Mechanical Engineering, University of South Carolina
Today’s energy technologies have been moving toward operating at near-limit conditions to achieve higher efficiency, lower emission, and fuel variability. Under these near limit conditions chemical kinetics and the thermo-fluid dynamics couple more distinctively in a reacting flow system. This talk discusses two such ‘near limit’ systems – “Liquid Phase” non-thermal plasma discharge and “Cool Flame” in multiphase configuration. The first part of the talk focuses on non-thermal plasma development in liquid phase. Non-thermal plasmas are non-equilibrium class of gas discharges where the electron temperature is very high, but the neutrals maintain room temperature condition. I will discuss the kinetic processes that drive the non-thermal plasma formation mechanism at nano-second time scales without any possible phase change taking place. The second part of the talk will introduce “Cool Flame” a phenomenon generally elusive in multiphase due to its very unique time scale. I will discuss the interplaying physicochemical processes that trigger “Cool Flame” behavior, and that can be controlled to purposely attain a “Cool Flame” burn in multiphase.
