Abstract: 

An experimental study has been performed to study the nature of breakup and penetration of liquid jets injected transversely into cross gas streams. The Schlieren technique was used to study the liquid jet breakup and penetration. This technique include concave mirrors and convex lens which will be useful when used with a high speed camera and a suitable light source. The resulting images are then processed and analyzed, using a processing software for studying the effects of various parameters on spray penetration. Experiment was carried out at ambient conditions and subsonic gas flow. Liquid-to-air momentum flux ratio (q- varied from 32 to 57) and Weber number (from 0.5 to 1) were the principal liquid jet operating parameters. Two modes of breakup have been noticed: column breakup and surface breakup. A correlation has been developed to predict the jet penetration with respect to q. Decrease of cross-flow velocity and increase of gas to liquid ratio are found to increase the penetration. Moreover, surface breakup produces droplets more than column breakup.
