Liquid mixing mechanisms include:
Bulk Flow:
Inducing large-scale fluid motion through the use of agitators or impellers, creating a circulatory flow pattern within the mixing vessel.
Turbulent Mixing:
Creating turbulence through high-speed impellers or baffles. Turbulence promotes mixing by causing chaotic and irregular fluid motion.
Laminar Mixing:
In low-viscosity liquids or at lower mixing speeds, mixing occurs in layers (laminae), with minimal disruption between layers.
Diffusion:
Molecular diffusion where molecules move from areas of high concentration to low concentration. This is slower compared to convective mixing but contributes to achieving final homogeneity.
Liquid Mixing Equipment
Agitators: Simple paddles or blades that stir the liquid.
Impellers: Rotating devices that create flow patterns within the liquid.
High-Shear Mixers: Use high-speed rotors to create intense mixing zones.
