【 摘 要 】

The gas turbine ignition chamber is a standout amongst the most basic segments to be unlined, in light of the fact that it must guarantee a steady operation in an extensive variety of air/fuel proportion and load. Among a few estimations engaged with the plan of a burning chamber, the reference region is the most vital physical parameter, particularly by the considerable effect on different measurements. As a rule, this parameter must be ascertained from an investigation of the impediments forced both compound responses and optimal design, i.e., in light of ignition process prerequisites and most extreme weight drop passable in the burning chamber, individually. In this way, the point of this paper is research the impact of the reference territory in the speed profile, in the temperature conveyance, in the blending procedure and in the fire conduct, as per the reference zone utilized as a part of the burning chamber. These numerical investigations were completed utilizing ANSYS CFX, contrasting them and the base esteem figured by Lefebvre [5], for a thermodynamic cycle of 600 kW gas turbine motor, conduced in Gate Cycle program. At last, it can be inferred that a few changes in the reference region figured by Lefebvre [4] creates better outcomes, particularly by enhancing the consuming procedure and the conduct of the fire.
