Luke’s research investigates the dynamics of ensemble-averaged turbulent, premixed flames. Specifically, this work focuses on identifying the ensemble-averaged turbulent flame position, displacement speed, and the sensitivity of the displacement speed to the ensemble-averaged flame curvature.

Jamie is working on the response of swirl flames to transverse acoustic excitation.

Gina’s research focuses on improving fuel injection and spray formation models for direct injection engine simulations. Towards this goal, she has developed a new experimental technique to quantify mean droplet sizes along the periphery of the fuel spray. These measurements are currently being used to inform the development of a spray breakup model, capable of linking injector nozzle details with the combustion process over a wide range of injection and in-cylinder conditions.

Postdoctoral Fellow

Brandon A. Sforzo received dual bachelors degrees in physics from Ithaca College and mechanical engineering from Cornell University in 2008, and continued to Georgia Tech for grad school, completing a MS in aerospace engineering in 2010 and his Ph.D. in 2014. Brandon’s doctoral research was on the topic of ignition performance for gas turbine engines and developed a dual experimental and modeling program to address the problem. Dr. Sforzo has continued working in the aerospace department as a postdoctoral fellow focusing on research in propulsion and energy. He works in the Ben T. Zinn combustion laboratory, investigating ignition performance of aviation fuels and also serves on the safety committee within the lab. Within the Space System Design Laboratory, he is currently investigating the feasibility of supersonic retro-propulsion as a planetary descent technology.  In addition to his scholarly roles, Brandon also enjoys many outdoor activities including: hiking, backpacking, camping, and gardening. To complement his gardening, Brandon is also a beekeeper and regularly volunteers with the Georgia Tech Urban Honeybee Project

Travis is experimentally studying the effects of transverse acoustic forcing on swirl-stabilized flames through the use of diagnostics such as sPIV, OH-PLIF, and Chemiluminescence.

Tan Zu works on (i) Development of phosphor-thermometry tool to characterize liquid-fuel jet-in-crossflow (JICF) at full engine take-off (i.e., supercritical) conditions. Mapping of fuel temperature and concentration patterns for industrial design and CFD-validation usages. (ii) Development of algorithm and benchmarking of existing methods for post-processing JICF spray images. (iii) Exploration of spray formation-processes in novel “twin-fluid JICF” fuel-injectors. (iv) Development of phosphor “thermo-velocimetry” system for characterizing Richtmyer-Meshkov instability in an inclined shock-tube.
