This research addresses the physics and chemistry of processes in gas turbine combustors and augmentors as well as pulsed-detonation engines through the study of isolated and interacting droplets, sprays, jet premixed and diffusion flames, swirling flames, and bluff-body stabilized flames. Continuing work requires experimental and theoretical approaches related to the following: (1) turbulent transport, mixing, entrainment, evaporation, droplet drag, drop-spacing effects, atomization, finite-rate chemistry, flame stability, ignition, and blow-out; (2) development of laser-based diagnostic techniques to support combustion and spray experiments; and (3) studies using either time-averaged or large-scale, time-dependent simulations. Numerous well-equipped laboratories contain small- and large-scale combustion tunnels and advanced laser apparatus designed for two-dimensional imaging, coherent anti-Stokes Raman scattering (CARS) spectroscopy; laser Doppler anemometry; phase Doppler particle analysis; laser-induced florescence techniques; hyperspectral absorption spectroscopy; ballistic photon imaging; and femto/picosecond experiments. Access to various combustion flow codes and the DOD ASC Major Shared Resource Center is available for theoretical studies.
