Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
The solidus temperature specifies the temperature below which a material is completely solid, [2] and the minimum temperature at which a melt can co-exist with crystals in thermodynamic equilibrium. Liquidus and solidus are mostly used for impure substances (mixtures) such as glasses , metal alloys , ceramics , rocks , and minerals .
Mixtures are one product of mechanically blending or mixing chemical substances such as ... As a homogeneous mixture, a solution has one phase (solid, liquid, or gas ...
where is the viscosity of the liquid mixture, is the viscosity (equation) for fluid component i when flowing as a pure fluid, and is the molfraction of component i in the liquid mixture. The Grunberg-Nissan (1949) [10] mixing rule extends the Arrhenius rule to
High-shear mixers are used in industry to produce standard mixtures of ingredients that do not naturally mix. When the total fluid is composed of two or more liquids, the final result is an emulsion; when composed of a solid and a liquid, it is termed a suspension and when a gas is dispersed throughout a liquid, the result is a lyosol. [16]
Suspensions are classified on the basis of the dispersed phase and the dispersion medium, where the former is essentially solid while the latter may either be a solid, a liquid, or a gas. In modern chemical process industries, high-shear mixing technology has been used to create many novel suspensions.
The term is most often applied to liquids but also applies to solids and gases. An example in liquids is the miscibility of water and ethanol as they mix in all proportions. [1] By contrast, substances are said to be immiscible if the mixture does not form a solution for certain proportions.
Liquid-solid fluidization has a number of applications in engineering [10] [11] The best-known application of liquid-solid fluidization is the backwash of granular filters using water. [12] [13] Fluidization has many applications with the use of ion exchange particles for the purification and processing of many industrial liquid streams ...
