Research activities in our group focus on the computational modeling and experimental analysis of turbulent and chemically reacting flows. Applications include propulsion systems, renewable energy, carbon sequestration, and high-speed and multiphase flows. Particular emphasis is directed towards improving the fundamental understanding of underlying physical processes involving the coupling between turbulence, reaction chemistry, pollutant formation and noise emission. Our research approach combines classical theoretical analysis tools (including linear stability analysis, rapid distortion theory, and stochastic models), numerical models, and the utilization of direct numerical simulation (DNS) results for the development, analysis, and validation of computational models. Current research interests include:
- Fundamental analysis of non-equilibrium and supercritical flows
- Heat-transfer and boundary layers
- High-order numerical techniques for chemically reacting flows
- Development of models for application to kinetics-controlled combustion, including auto-ignition, low-temperature combustion, and combustion-dynamic processes
- Particle-laden flows and atmospheric entry
- Heterogeneous flows in micro-, meso-, and nano-porous flows
- CO2 capture and sequestration
Another active area of research involves the experimental analysis of ultrafast non-equilibrium processes using X-ray diffraction and spectroscopy, specfically focusing on sub-picosecond physico-chemical processes in complex fluids and chemical systems. For this, we're closely working with the SLAC National Accelerator Laboratory, the Advanced Light Source at LBNL and other facility to perform X-ray experiments.
