Turbulence Interactions in Single- and Multi-Phase Turbulent Mixing and Combustion Processes.
Abstract
Turbulent multiphase flows (particle-laden jets, particle-laden flows in ducts, sprays, etc.) have technical applications for the combustion processes of airbreathing propulsion systems, and solid and liquid rocket motors. This report describes an upgrade of a single channel laser Doppler anemometer (LDA) to provide critical measurements needed to gain a better understanding of this class of multiphase flows. The upgrade yields a system which can be configured in several ways: a phase-discriminating LDA which provides either two phase-velocity components at a single point, or phase velocities at two points which are independently transversable; and a phas-Doppler LDA which can provide two-component particle (or drop) size and velocity information at a single point. All systems can yield particle (or drop) number fluxes. The arrangement of these systems is described along with some representative results using the phase-discrimination configuration. Keywords: Dilute dispersed flows; Laser Doppler anemometry; Multiphase flow; Particle-laden jet flow.
