Jet flow phenomenon is one of the most important basic flows in the thermo and fluid mechanics because it includes the free and wall bounded turbulent shear flows and largescale vortex structures. In addition, it is used widely in the field of industry for heating, cooling, mixing, diffusion, propulsion, and material processing. By the way, in order to improve the mixing and diffusion characteristics between the jet and surroundings there are many trials, for example, by using of various non-circular nozzles. In this study, the flow characteristics, mixing and diffusion properties, of the submerged free jet from the petal-shaped special nozzle with 6 petals are examined experimentally. It is expected that 6 petal-shaped free jet will have a good mixing and diffusion characteristics because of a large wetting perimeter, and forming of large vortex structures.
