A Numerical Simulation of Incompressible Free Surface Laminar Flows by the Artificial Compressibility Navier-Stokes Solver
Abstract
자유표면ㅇ르 가진 층류유동의 해석을 위하여 Artificial Compressibility Method(이하ACM)을 도입하여 계산을 수행하였다. 수치계산은 양해법을 사용하였으며 Backward Facing Step와 Driven Cavity문제에 대한 계산예를 통하여 기법의 타당성을 검증하였다. 본 계산기법을 자유표면 유동문제로 확장하여 적용한 결과, 자유표면의 변위, 유동장, 압력분포에 미치는 자유펴면의 영향등을 대체적으로 잘 파악할 수 있었다.
In the present paper, Artificial Compressibility Method(ACM) is adopted for numerical analysis of laminar flows with free surface.

An explicit algorithm is enployed in numerical computation and its validity is checked through some example calculations for the well known Backward Facing Step Flow and Driven Cavity problem.

Furthermore, the present method is applied to the free surface laminar flow problem, the main subject of the present study, in which flow pattern analysis is carried out for a two dimensional with various bump shapes.
