축류 압축기 날개열의 팁 영역에 관한 3차원 수치해석을 통한 난류모형 비교
Comparison of Turbulence Models through Three Dimensional Numerical Soultion for the Tip Region of an Axial Compressor Cascade
초록
A pressure-based Navier-Stokes numerical solver was used to compare solutions of the k-ε/RNG k-ε turbulence models. An efficient grid generation scheme, the transient grid generation with full boundary control, was used to solve the flows in the tip clearance region. Results indicate that the calculations using k-ε model captures various phenomena related to the tip clearance with good accuracy.
