A Large-Eddy Simulation (LES) with a two-way coupling is used to study bubble-liquid two-phase confined jets in a two-dimensional channel. The results show the large-eddy vortex structures of both liquid flow and bubble motion, the shear-generated and bubble-induced liquid turbulence. For comparison, the second-order moment (SOM) modeling was also carried out for the same case. Both LES and SOM results indicate much stronger bubble fluctuation than the liquid fluctuation, the enhancement of liquid turbulence by bubbles even for the higher velocity case. Both shear production and the production due to bubble-liquid interaction are important for the liquid turbulence generation in the case studied. The LES statistical results and the SOM simulation results are in qualitative agreement with each other.
