T-junction piping system is used to mix the fluids in different temperature. If the temperature fluctuation generated in the mixing process is transmitted to the structure, it may bring thermal fatigue in the structure. Here, "Turbulence promoter" was considered to reduce the amplitude and the low frequency component of the temperature fluctuation. In this study, numerical simulation under iso-thermal condition is conducted to clarify the change of the flow pattern and the mixing mechanism due to the promoter and to optimize the promoter configuration. As the result, we clarified that the horseshoe eddy can be controlled by the promoter and appropriate height of the promoter was found to reduce the horseshoe eddy.
