The geometry of the T-mixer has a great consequence on the fluids input dynamics and consequently influences the size distribution and elemental composition of outcoming nanoparticle products. The Tmixer with non co-axial inputs considered in this work (Figure 1) is designed in such a way that the entering jets form a vortex in the uppermost fluid contact area and generate a turbulent swirling flow downward the main output tube. The fluid velocity profile reflects an instant formation of a vortex including zones in the fluids inputs with high local Reynolds numbers; which size depends on the amount of energy injected into the system. This work aims validation of the numerical model of the T-mixer performance: by experimental measurements and numerical calculations of the length (Li) required for obtaining the quasi-perfect reagents micromixing. We used the Computational fluid dynamics (CFD) code to simulate the fluids flow in the T-mixed within the k-ε turbulence model using Ansys Fluent software. The obtained experimental and numerical values of the micromixing length Li are in a closed agreement.
