Study on mixing behavior in a tee piping and numerical analyses for evaluation of thermal striping

Kamide, Hideki ; Igarashi, Minoru*; Kawashima, Shigeyo*; Kimura, Nobuyuki; Hayashi, Kenji

Water experiments were carried out for thermal hydraulic aspects of thermal striping in a mixing tee, which has main to branch diameter ratio of 3. Detailed temperature and velocity fields were measured by a movable thermocouple tree and particle image velocimetry. Flow patterns in the tee were classified into three groups, which had own temperature fluctuation profiles. The power spectrum density (PSD) of temperature fluctuation showed an unique profile, which is normalized by St number, when the flow velocity ratio and flow pattern was identical. Numerical simulation based on finite difference method showed alternative vortex development behind the jet from the branch pipe in a case of wall jet. Mixing behavior in the tee was discussed based on the measured data and the simulation.
