Abstract Thermal fatigue crack may initiate at mixing tee where high and low temperature fluids flow in and mix. In order to prevent piping failure caused by thermal fatigue, an evaluation procedure of fluid temperature fluctuation at mixing tee using numerical simulation has been de veloped. This paper compared results of three computational grids of different resolution and discussed the effect of the grids resolution on predictions. The same simulation conditions were set same as WATLON experiments perf...
