Fractional step method를 이용한 엔진내부유동의 수치해석
Numerical study on in-cylinder flow of a reciprocating engine using a fractional step method
- 발행 : 2000.11.02
초록
A numerical code which can simulate unsteady, incompressible and 3-dimensional flows in an engine cylinder has been developed. The governing equations based on the cylindrical coordinate are discretized by the finite volume method with staggered variable arrangements. A geometric conservation rule is also incorporated into the simulation code in order to deal with a moving boundary problem. For the unsteady simulation, a fractional step method is adopted. The law of wall is applied to the wall boundaries and standard
