Static mixers or motionless mixers are a special type of mixer that achieve intermaterial area increase without any moving parts. Static mixers include both laminar and turbulent flow regimes, mixing of high and low viscosity fluids, such as in-line blending of solvents, polymer blending, gas-gas mixing, and dispersion of immiscible fluids. The description here is restricted to mixing of similar fluids in laminar flows. These types of mixers are designed to produce increase in intermaterial area per unit volume, a SUB v (reduction in striation thickness, s), by flow reorientation and material subdivision in such a way that a SUB v increases predictably in each of the repetitive flow units of the mixer. The consecutive flows are produced by a periodic pattern of non-moving solid surfaces inserted in the flow. (from paper)
