| Abstract: | The experimental investigation of the air atomization injector characteristics for the gas turbine was conducted. The injector fuel supplying characteristics, the change features of spray cone angle, droplet size and its distributions law were obtained. The flame tube of the injector in the intermediate operation condition was numerically simulated. The track of the oil droplet in the flame tube and the nose aiO%w fields and the density fields were calculated. |
