Abstract:
For the improvement of gas turbine engines, the performance of gas turbine
engines increases when increasing the turbine inlet temperature. At present, the turbine
inlet temperature has already been higher than the melting point of the turbine blade
material. Therefore, the trailing edge of gas turbine blades requires the effective internal
cooling methods because the narrow shape of the trailing-edge region constrains the
internal cooling passage. The impingement of a rib-roughened cooling technique is
applied to reduce the turbine blade temperature in order to prevent the turbine blade
failures. This paper presents the 3D steady numerical study of the flow and the cooling
effectiveness indicated by the Nusselt number distribution at the 11 target surfaces
based on the Reynolds-Averaged Navier-Stokes (RANS) equations coupled with the
energy equation using 5 turbulence models which are Spalart-Allmaras, Wilcox k-ω,
SST k-ω, realizable k-ɛ with enhanced wall treatment and RNG k-ɛ with enhanced wall
treatment. The comparison of the results using 5 turbulence models under the static
condition with the experimental data is conducted for the model validation. The Wilcox
k-ω turbulence model is qualified and employed for this work. For investigation of the
flow and the cooling effectiveness on the rotating turbine blade, only the Wilcox k-ω
turbulence model is applied to the same geometry with the rotational velocity of 3000
rpm. The result reveals that the cooling performance of the turbine blade is affected by
the centrifugal force, that is, the cooling effectiveness of the rotational case is 22-59 percent
lower, compared to the static case.
