FLAME SHAPES AND HEAT TRANSFER CHARACTERISTICS OF AN IMPINGING FLAME JET

Shankar Badiger, T.R. Anil, V.V.Katti

Abstract: Experiments were conducted on premixed LPG/air circular flame jet impinging normally on a rectangular flat surface. The heat transfer characteristics and flame shapes have been studied by varying the different parameters like equivalence ratio (0.8, 1, 1.2 and 1.4) and Reynolds number (500, 600, 800, 1000, 1200 and 1500). A circular flame jet impinged on to water cooled calorimeter made up of spiral rings. The increase in the height of the fame was observed by increasing both Reynolds number and equivalence ratio. The heat flux was increased by increasing the Reynolds number and also by increasing equivalence ratio.
