Abstract

Flow and scalar mixing characteristics for turbulent flow in a counter-type T-junction have been examined experimentally. The T-junction was modeled by a mixing tee with square cross sections, in which the mixing channel was connected with the main and counter channels at right angles. Detailed characteristics of the velocity and concentration fields after the mixing have been investigated using simultaneous measurements by PIV and PLIF with high spatial/time resolutions. The three-dimensional characteristics of the velocity field and its influence on the concentration field in the mixed flow were clarified. Moreover, the mechanism of turbulent mixing of two fluids was analyzed based on the turbulent mass fluxes.
