In a pressure atomizer-type combustor of gas turbines, numerous factors in the fuel spray have influence on the combustion performance and on the pollutants emission. Factors such as evaporation rates and trajectories of fuel droplets are very complicated to analyze as a cluster, therefore, the authors have performed simplified calculation in the case of single droplet under high-pressure, high-temperature conditions. The remarkable results are as follows: 1.Equilibrium temperature of a droplet increases with the increasing temperature of the ambient air and the period to attain the equilibrium temperature decreases with the same condition. 2.Evaporation period of a droplet increases with the increasing pressure at 573K of the ambient temperature. But the pressure effect on the evaporation period is inverted above 673K. 3.Heating period occupies a considerable part of the total life-time. 4.Relative velocity of droplet and air-stream decreases rapidly and the penetration distance becomes shorter at high pressure condition. It is mainly due to density of the ambient air. 5.Assuming that the initial diameter of droplet is 100μm, almost all of penetration distance of the droplet is in the heating period. 6.Effect of ambient temperature on the trajectory is small at atmospheric pressure, but is considerable at high pressure condition. 7.Influence of the swirler air-stream on the droplet velocity becomes large for a slow droplet. In this case the droplet is accelerated by the air stream. |
