FUEL ATOMIZATION AN INNOVATIVE SIMULATION

THE PROPOSED WORK CONSISTS OF A THEORETICAL AND EXPERIMENTAL INVESTIGATION TO DEVELOP A FUEL ATOMIZATION CODE WHICH TRACKS THE BEHAVIOR OF THE FUEL FROM THE INJECTION ELEMENT TO ITS TOTAL EVAPORATION AND COMBUSTION. THE PROPOSED ATOMIZATION METHOD USES AN INNOVATIVE VORTEX DYNAMICS ALGORITHM WHICH BASED ON FUNDAMENTAL PRINCIPLES WILL ALLOW DISTURBANCES TO GROW AND BREAK INTO LIGAMENTS, AND ULTIMATELY INTO TRANSITIONAL LIQUID ELEMENTS AND DROPLETS. A STATE-FO-THE-ART TRANSIENT DROPLET VAPORIZATION MODEL WILL BE USED TO PREDICT THE GASIFICATION OF THE FUEL. THE MODEL SOLVES THE GOVERNMENT GAS-PHASE EQUATIONS, INCLUDING SOURCE TERMS FOR VAPORIZATION AND COMBUSTION, BY MEANS OF FINITE DIFFERENCES. HOLOGRAPHY WILL BE EMPLOYED TO EXPERIMENTALLY QUANTIFY THE NATURE AND GROWTH RATE OF THE DISTURBANCES, THE DISTRIBUTION OF LIQUID ELEMENTS, THE EVAPORATION RATE, AND THE COMBUSTION REGION OF SPRAYS RELEVANT TO GAS TURBINE COMBUSTORS. THIS WORK, IF CARRIED THROUGH PHASE II WILL RESULT IN AN ADVANCED FUEL ATOMIZATION AND COMBUSTION CODE FOR GAS TURBINE COMBUSTORS.
