벌류트 압축기내의 난류유동 수치해석 = Numerical Analysis of Turbulent Flows in the Scroll Volute of Centrifugal Compressor

다국어 초록 (Multilingual Abstract)

The flow analysis was made by applying the turbulent models in the scroll volume of centrifugal compressor. The $k-{\varepsilon}.\;k-{\omega}$, Spalart-Allmaras and reynolds stress models are used in which the hybrid grid is applied for the simulation. The velocity vector the Pressure contour. the change of residual along the iteration number. and the dynamic head are simulated by solving the Navier-Stokes equations for the comparison of four example cases.
