Abstract
Large-eddy simulation (LES) of particle-laden, swirling flow in a coaxial-jet combustor is performed. A
mixture of air and lightly loaded, spherical, glass-particles with a prescribed size-distribution enters the
primary jet, while a swirling stream of air flows through the annulus. The incompressible, spatially filtered
