[기계] Dynamics and Morphology of Expanding Spherical Flames
1. 제 목 : Dynamics and Morphology of Expanding Spherical Flames
2. 연 사 : C. K. Law(Department of Mechanical and Aerospace Engineering
Princeton University)
3. 일 시 : 2009년 6월 4일 (목) 17:00 ~ 18:30
4. 장 소 : 차세대자동차연구센터 2층 세미나실(314동 211호)
5. 내 용 :
The dynamics of expanding spherical flames is of interest to a variety of practical and natural phenomena, such as the intentional and accidental spark ignition of a combustible mixture, and the explosion of the supernovae through the deflagration to detonation transition of the nuclear flame. Fundamentally, these processes are characterized by strong stretch effects during the early stage of flame propagation, and flamefront cellular instability during the later stage. The seminar will cover topics on the minimum critical radius for successful ignition, the nonlinear variation of the flame propagation speed with the stretch rate, transition to cellularity induced by hydrodynamic and diffusional-thermal instabilities, self-acceleration and the self-similar nature of the propagation, transition to detonation, and the formation of spiral waves and target patterns over the expanding flame surface as manifestations of diffusional-thermal pulsating instability. Theoretical and experimental results will be presented in a synergistic manner to demonstrate the rigor and beauty of combustion science.
