Combustion and Mixing Studies in Compressible Flows.
Abstract
Single and two phase fuel injection into compressible flows was studied. Mixing was measured under a variety of injection conditions as governed by injector geometry and fuel chemistry, phase, velocity, temperature and pressure. The impact of flow conditions on the state of mixing was also investigated. Several diagnostic methods were used, including optical diagnostic techniques and mechanical probing. Combinations of mechanical probe measurements were used to calculate such flow properties as Mach number, velocity, static temperature, and species concentration. For mixing studies, both the scalar and vector quantities were measured to assess the Schmidt number effect Information obtained using laser diagnostic techniques was compared with the probe measurements. Results of the comparisons suggest that data obtained through laser diagnostic techniques and probe measurements can complement each other, contributing to the development of a broad understanding of the physical processes of running under a variety of conditions. These basic mixing studies have led to the successful development of several mixing enhancement schemes, which have been tested and reported elsewhere.
