Numerical analysis of mixing performance of optical micro rotor

1.仅考虑流体的扩散作为一种混合机制，发现在扩散系数Γ=1.0×10；-12；m^2/S和Γ=1.0×10&lt；-11；m^2/S时，混合比随进口速度的增加而增大，而当Γ=1.0×10&lt；-10；m^2/S时，混合比与进口速度无关。同时考虑了流体的扩散和光学转子的作用，得到了混合比对雷诺数和ST数的相似规律。在Γ=1.0×10^&lt；-12&gt；m^2/S和1.0×10^&lt；-11&gt；m^2/S时，混合比在ST=3.0时达到最大值，在Γ=1.0×10^&lt；-10&gt；m^2/S时，在ST=0.5 3时达到最大值。在Γ=1.0×10^&lt；-12；m^2/S时，最大值随转速的增大而增大，随进气速度的减小而增大。在Γ=1.0x10^&lt；-11；m^2/S时，这一比例与转子的存在无关。但在Γ=1×10^&lt；-10&gt；m^2/S时，转子的存在降低了掺混比。

1. Considering only the diffusion of fluids as a mixture mechanism, it is found that at diffusion coefficient Γ = 1.0 × 10^<-12> m^2/s and Γ = 1.0 × 10^<-11> m^2/s, the mixture ratio increases as the inlet velocity while at Γ = 1.0 × 10^<-10> m^2/s, the ratio does not depend on the inlet velocity.2. Considering both the diffusion of the fluids and the optical rotor, the similarity law of the mixture ratio with respect to Re number and St number is found. Also it is found that at Γ = 1.0 × 10^<-12> m^2/s and 1.0 × 10^<-11> m^2/s, the mixture ratio becomes maximum at St=3.0, and that at Γ = 1.0 × 10^<-10> m^2/s, the maximum is reached at St=0.5.3. At Γ = 1.0 × 10^<-12> m^2/s, the maximum ratio increases with increasing rotation speed and with decreasing inlet speed. At Γ = 1.0 × 10^<-11> m^2/s, the ratio does not depend on the existence of the rotor. However, at Γ = 1.0 × 10^<-10> m^2/s, the existence of the rotor decreases the mixture ratio.
