Numerical simulation of the mixing behaviour of hot and cold fluids in the rectangular T-junction with/without an impeller

Kexin Huang et al.

Summary: Thermal stratification is the main cause of thermal fatigue failure in rectangular T-junctions. By setting an impeller with a constant rotation speed, the mixing behavior of hot and cold fluids can be improved, and various flow patterns including wall jet, deflecting jet, and impinging jet can be observed. The relationship between mixing length and blade diameter is not monotonic, and the optimal operating point is around D-p* = 0.5 for impellers with 2 blades.
