In order to increase the calculation speed for viscosity calculations based on CS theory, which is important in e.g. compositional reservoir simulations, while keeping the accuracy of the CS method, Pedersen et al. (1984, 1987, 1989) [17] [18] [2] proposed a CS method that uses a simple (or conventional) CS formula when calculating the reduced ...
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 ...
Dilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution. To dilute a solution means to add more solvent without the addition of more solute. The resulting solution is thoroughly mixed so as to ensure that all parts of the solution are ...
When a nozzle is used for cleaning, the impact or pressure is called impingement. As with all spray patterns, the unit impact decreases as the distance from the nozzle increases, thereby increasing the impact area size. The spray impact, , depends on the volumetric flowrate Q and pressure drop according to the equation below. The nozzle type ...
The mixing time will determine the quality of the random mixture. However, if powders with particles of different size, density or shape are mixed, segregation can occur. [ 4 ] Segregation will cause separation of the powders as, for example, lighter particles will be prone to travel to the top of the mixture whereas heavier particles are kept ...
By far the most frequently used products are formulations for mixing with water then applying as sprays. Water miscible, older formulations include: EC Emulsifiable concentrate; WP Wettable powder; SL Soluble (liquid) concentrate; SP Soluble powder; Newer, non-powdery formulations with reduced or no use of hazardous solvents and improved ...
The spray drying technique was first described in 1860 with the first spray dryer instrument patented by Samuel Percy in 1872. [citation needed] With time, the spray drying method grew in popularity, at first mainly for milk production in the 1920s and during World War II, when there was a need to reduce the weight and volume of food and other materials.
Mixer agglomeration: Mixer agglomerators agitate the powder with the use of a blade inside a bowl. The geometry of mixer agglomerators vary widely. The blade can be oriented vertically, horizontally or obliquely. Shear is variable, and the wetting solution is sprayed over the bulk of the powder as it is mixing.
