Experimental study of turbulent mixing in a T-shaped mixer
T-shaped mixers are workhorses for rapid mixing across scales, yet turbulent regimes remain underexplored experimentally. We scale up T-shaped mixers from sub-millimeters to centimeters, and implement flow measurements using techniques of particle image velocimetry and planar laser-induced fluorescence across laminar to turbulent regimes, validated against direct numerical simulations. We successfully replicate the flow characteristics in low-Reynolds-number regimes from micro-scale devices in literature, and also reveal enhanced turbulent mixing in the outlet channel, offering new insights into mixing dynamics at multiple scales.
