原创 than the droplet velocity.

 

Mixing caused by diffusion and convection of the main eddy diffusion, molecular diffusion between different liquids to increase the surface area reduces the diffusion distance, thus shortening the time of molecular diffusion. If the viscosity of the liquid to be mixed is not high, you can not reach a long mixing time randomly mixed state; if high viscosity, it would take a longer mixing time.

For the density, composition is different, immiscible liquid, mixing shear generated turbulence and a strong density of the liquid would tear it into small droplets and dispersed to the main liquid. Produced by mixing the liquid flow rate must be greater than the droplet velocity.

A small amount of insoluble solid powder mixed with liquid mechanism, different composition and density, immiscible liquid mixture of the same mechanism, but can not change the mixing solid powder particle size. If it can not be mixed before settling velocity of solid particles smaller than the liquid flow rate, regardless of mixing method are not form a uniform suspension.
