Experimental Investigation and Mathematical Modelling to Study thePremixed Laminar Flame Propagation

Abstract

n the present work, experiments are conducted on a newly designed flame propagation testunit using burners of different geometries (L/D ratio) at different air-fuel ratios to calculate theflame speed. From the experimental data obtained, design plots are drawn to study the flamestability zone under different conditions.  Using the above test results and standard mathematicalcurve fitting techniques for a function of two variables, an equation has been derived which canbe utilised by the designers to design an optimum burner for premixed flames which providesstable flame with maximum flame speed for the best burner geometry.
