The Combustion engineers at CFDRC routinely perform unsteady Large Eddy Simulation (LES) combustion calculations to predict combustion instability and other time-dependent combustion phenomena.We can assess active/passive fixes in lean premixed industrial combustors, furnaces, ramjets, and high performance military combustors.

CFD Research Corporation performed contracts totaling $2.75 million from DOE NETL and AFRL to develop the combustion LES software. Focus areas were gaseous fuel and low emissions for DOE NETL, and liquid fuel and combustion instability for AFRL. Additional contracts in excess of $2.2 million have been obtained from the Navy (NAVAIR), Air Force (AFRL and AEDC), and NASA (GRC) to further develop and validate the models, and apply the software to practical geometries. Over $10 million worth of development contracts for Spray Combustion LES.
