The influence of several parameters such as the inclined vanes of diffuser and the sense of rotation of the single or multiple swirling jets, their number and their arrangement on the flow resulting thermally was experimentally investigated. Experiences concerning the fusion of several jets show that gas mixtures are clearly more homogenized under swirling influence. The results of this study show that the gap between the jets and their sense of rotation relative to the central jet, affects the quality of homogenization jets blown. Compared with the single jet, under uniform velocity and temperature, the multi-swirling jet with an angle of greater openness ensures a stable temperature distribution.
