A STUDY ON THE INFLUENCE OF SHAPE OF BURNER ON THE MEASUREMENT OF THE LAMINAR BURNING VELOCITY

Abstract

In this research, three burners are manufactured in different shapes (rectangular, square and circular). By optical Schielren system, velocity of laminar flame diffusion is measured for the three burners to the Iraqi Liguid Petrol Gas (LPG) and the beforehand mixed air at the laboratory condition (1 atm, 298o K) and for wide and equal range of equivalent ratios (Ф) in the three burners, and using the equivalent ratios as a comparison factor in this research. The experimental results were performed and the effect of the shape of burners on the laminar flame speed was studied. The results in this research gave a good agreement with the litretures.The agreement refers that there is a good accuracy in the method of calculation and measurement used in this research
