Fundamental Studies on Spray Combustion and Turbulent Combustion
Abstract
Four major research tasks were performed during the year. Several prototype liquid atomization experimental designs were developed and tested, and the pulse visualization system was demonstrated. A nonlinear theory for liquid sheet deformation has been developed that predicts vortical rollup of the liquid-gas interface and allows for a rough estimate of early ligament dimensions in the atomization process. The turbulent reactive flow study identifies that the mixing and entrainment rates are identical on the high-speed and low-speed sides of a constant-density mixing layer. The formation, merging, and pairing of vortical structures is also predicted. Variable property effects have been included in the vaporizing droplet theory providing significant modifications on drag coefficients, Nusselt number, and Sherwood numbers. Modified correlations for higher transfer numbers are being developed and interacting droplets are considered. Keywords: Spray combustion, Turbulent combustion, Atomization.
