A LES technique is used for investigation of jet mixing processes with heat transfer in a turbulent pipe flow. Predictions were validated for different test problems. Influence of velocity, density, kinematic viscosity and temperature in a co‐flow and in an admixture as well as the effect of the Reynolds number on mixing were studied. Two efficient methods of mixing control, namely periodic injection and swirling jets, were investigated.
