| Abstract | ||
| In this paper the laser beam (Ne-He type) with wavelength (0.6328 mm) is used to measure laminar flame speed for Methane-Air pre-mixture by limit the flame position in the combustion chamber. This is achieved by cutting the laser beam the flame perpendicularly at certain distances and calculate the time that take of flame to cross the certain distances. All measurements were done at pre-pressure period .A density ratio method was employed to obtain the laminar burning velocity. Comparison the results with other published results indicate a reliable technique that is used in the present work | ||
