Experimental Investigation of Flame Speed of Fuel–Air Mixture for Varying Air/Fuel Ratio
The present investigation aims to study the flame dynamics of LPG (fuel) and air mixture. An experimental setup of P.A. Hilton’s Flame Propagation and Stability Unit is used to determine the flame speed of LPG and air mixture at varying A/F ratio using flame tube method. Flame tubes of four different diameters are used to study the effect of tube diameter on flame speed at various Air/fuel(A/F) ratio. It was observed that flame speed tends to increase with increase in tube diameter for varying A/F ratio and vice versa. Flame speed increases with increasing A/F ratio till stoichiometric ratio is reached, after which it starts decreasing again.
