dc.description.abstractInfluence of geometry on the mixing mechanism and efficiency is studied by comparing Opposed Jets of Cylindrical and Prismatic shapes, having the same hydraulic chamber diameter by 3D Computational Fluid Dynamics (CFD) models. For the test case, same Reynolds numbers of the jets were provided. The comparison is assessed by hydrodynamics, turbulence parameters and mass transfer inside the mixing chambers. While the hydraulic diameters of the chambers set as equals, the thickness of the jets of the T-Jets mixers set as the diameters of the jets of the Confined Impinging Jets, which resulted in non-equal hydraulic diameters of the Jets. The power spectra of the x and y velocities for T-Jets showed a similar peaks as in 2D chambers, however without the spread of the energy. The results suggests that for T-Jets, Reynolds numbers of the jets alone is not enough to describe the mixing inside the chamber, but the thickness of the jets is also an important parameter since different values of jets thicknesses and depths can provide the same hydraulic diameter. Finally, this study shows that on one hand CIJ promotes a more intense striation of the initial flow scales when compared to the T-jets, on the other hand the latter promotes a broader impingement region and allows larger inlet areas, i.e. higher throughputs, for the same initial scale. The choice of the mixer should then be the trade-off between these two factors. For a better comparison, the same hydraulic diameters of the jets giving the same Reynolds numbers should be investigateden_US
