Plants have many tee pipes where a hot fluid and cold fluid flow into each other and mix. The mixing of hot and cold water can cause a fluid temperature fluctuation which leads to the temperature flutctuation of the inner pipe wall, so characteristics of this flucuation in the mixing tee pipe were investigated through experiments. This paper shows the three mixing flow patterns in the tee pipe, i. e. stratified flow, turned jet and wall jet, the location of the maximum fluid temperature fluctuation and fluid temperature fluctuation characteristics downstream from the tee pipe. The experiments showed that characteristics of the fluid temperature fluctuation were largely related to the flow pattern in the tee pipe. The flow pattern of the turned flow in the tee pipe could suppress the fluid temperature fluctuation.
