1. 제 목 : Dissipative Mechanism in Godunov-type Schemes
2. 연 사 : Dr. Kun Xu (HongKong University of Science and Technology)
3. 일 시 : 2000년 2월 22일 (화요일) 14:30
4. 장 소 : 301동 1512호
5. 내 용 :
In this talk, we are trying to answer some fundamental questions on the computation of compressible gas dynamics.
1. What is the reason for the shock capturing schemes to capture shocks?
2. Where is the numerical dissipation coming from?
3. What is the physical consequence from the numerical dissipation?
As a result, some pathological phenomena of the shock capturing schemes, such as the post-shock oscillations and carbuncle phenomena will be physically explained.
