메탄-공기 예혼합화염의 구조변이에 대한 수치적 연구

A numerical method for the analysis of CH₄-Air premixed flame is presented with the scrutiny into the flame structure and propagation behavior. The continuity, momentum, energy and mass fraction equation with standard k-e turbulence model were solved with ANSYS-Fluent. It is confirmed with comparison to experimental results that flame structure changes in the order of hemispherical, flat and tulip flame. The detailed analysis on each flame structure is conducted using vectors and contours.
