Abstract
Abstract Laminar burning velocity for ( L.P.G - Air ) premixed mixture was measured by using square burner and the technique of area method with range of equivalent ratio ( 0.883-1.233 ) . To obtain a stable flame front with flat faces a square burner was designed and manufactured which give two dimensional flame front the burne , rim was designed with flame holder to reduce the effect of burner rim aerodynamic , the flame photography has been obtained with high resolution by using Schieren photography . The flame thickness and the quenching distance were calculated depending on the dimensionless aspects using variable values of ( pecelt number ) from the later researches.and the stability limits which described by flash back and blow off was determined experimentally The actual dimensions of the flame structure were obtained from schlieren photography using the computer program ( Adobe photoshop ver.6 ) with supply an accurate tool for dimension measurements and photography treatment . The result of the present work showed a good agreement with those previously published , the result of this work given in appendix ( A ) .
