Description
Summary:The motion of air and solid particles is examined in a fluidically oscillating slot jet using time-averaged and cycle-resolved laser Doppler anemometry measurements. These measurements reveal the time dependent relative velocity magnitudes between the phases as well as the detailed nature of the flulidcally oscillating slot jet. Temporal phase differences between the gas and solid phases ranged up to 40 degrees for jet oscillation frequencies up to 50 Hz. The results indicate that the fluidic nozzle is an effective particle spreading device and the fuel injector attributes are inherently present such as enhanced mixing and low velocity regions for flame anchoring.
