Abstract:

According to the mixing principle of Tesla-type micromixer, Three-dimensional numerical simulation was carried out with adoption of Computational Fluid Dynamic software in this paper. The nite volume method was used to disperse the three-dimensional steady incompressible N-S equations. The effect of mixing performance was analyzed when changing the structural parameters of this type micromixer. Mixing index is measure standard used to evaluate the degree of mixing. Our studies show that the structural parameters, e.g. different aspect ratio of microchannels and the inflow angle of separation channel, have an important effect on the mixing performance. Taking account for the relation between mixing intensity and pump power consumption, the optimum structure parameters of Tesla-type micromixer are B/W=0.75 and α=55°.
