This study deals with the interaction of three turbulent swirling jets according to two basic configurations: A2, where a hot middle flux is diffused in a reverse way of less hot adjacent fluxes and B2 where these three flux is are at the same blowing temperature. The velocities and temperatures measurement, in the experimental premises are obtained thanks to the hot wire anemometry and digital thermometry. The radial temperatures are greater, for a important blade inclination whereas The axial temperatures decrease and so much more for the A2 configuration.
