Abstract

In this paper numerical simulation of a thermal state of a sector of the modern gas-turbine engine turbine split ring in the conjugate heat transfer statement in ANSYS CFX 12.1 is executed. Experimental verification of the received results on the basis of metallographic researches of sectors and modern gas-turbine engine tests is spent. A number of actions for decrease in temperature of sector on 45K in comparison with an original design are offered.

Keywords:

high pressure turbine; sector of the split ring; thermal state; numerical simulation
