Özet:

 


We undertake a numerical three-dimensional study of the interaction of a
row of discrete jets in a wall with a transversal compressible flow for
different injection rate (M=0.3, 0.5, 0.7 and 1.4). This simulation is applied
to the stator blade of the CFM56 engine and is performed using the
computational fluid dynamics (CFD) simulation tool, with CFX.13 software.
Reynolds averaged Navier-Stokes equations were solved using a finite volume
method. Turbulence closure was achieved using the Shear-Stress Transport model
(SST). The velocity and temperature distributions and the film cooling
effectiveness are presented and discussed. We found that the best cooling
effectiveness occurs at M= 0.7. More, for higher
injection rate (M=1.4), the results show the existence of two counter- rotating
vortices. These vortices transport the hot gas in the jet and thus degrade the
protective wall.
