압축성 유동 해석을 위한 압력 기반 해석자의 개선된 알고리즘 개발 = Development of Improved Pressure-Based Solver Algorithm for Compressible Flow

다국어 초록 (Multilingual Abstract)

In this paper, an improved pressure-based computational fluid dynamics algorithm for numerical analysis of compressible flow with shock waves was described. For this purpose, the Kurganov-Tadmor flux splitting scheme, which is mainly used in density-based solvers, was applied to a developed pressure-based solver and a verification analysis of compressible flow problems were performed using the developed solver. It was confirmed that the developed solver had the similar analytical ability with that of the other numerical codes through the analysis of the 2D oblique shock wave and the backward-facing step problem in the supersonic flow region. In order to verify the analytical ability for the transonic flow region of the developed solver, 2D RAE2822 airfoil and 3D Onera M6 wing were analyzed and compared with results of experiments and other numerical analysis codes. It is confirmed that the analytical ability of developed solver in the high speed flow region such as supersonic and transonic is somewhat improved than the commercial analysis package and is similar to the density based in-house CFD code.
