INVESTIGATION OF AN ANNULAR VAPORIZING COMBUSTION CHAMBER APPLIED TO SMALL-SIZED GAS-TURBINE ENGINES,

Abstract

In-line-flow and counter-flow annular combustion chambers were tested. A slotted model with quartz inspection windows was also used. The fuels were T-1 kerosene and B-70 gasoline (for slotted model). The models (about 16) differed in the dimensions of the vaporizing tubes and air nozzles. Analysis of the primary zone of the chamber shows the following processes: vaporization of part of the fuel and its mixing with the air in the vaporizing tubes, spreading out of the fuel-air mixture along the bottom of the fire tube with further vaporization and impoverishment of the mixture, and turbulent diffuse combustion.
