Gas-gas mixing or gas blending is the mixing of gases for a purpose where the final gas mixture is specified. A gas mixture is defined in a molar gas fraction by percentage, parts per thousand, or parts per million. WitrynaAxial flow impellers have an up-down flow pattern i.e. parallel to the impeller shaft. Commonly used for low to medium viscosity products, their low shear characteristics …

WitrynaHydrofoil impellers are commonly referred to as high efficiency impellers since they are designed to maximize fluid flow and minimize shear rate, and therefore these impellers are popular in a majority of mixer installations. The hydrofoil impeller has 3 or 4 tapering twisted blades, cambered and sometimes provided with rounded leading edges. WitrynaThe impellers flow patterns affect the results of mixing process. The type of impeller influence the flow patterns in the fluid which gives a variation in flow pattern the two type of flow patterns are axial and radial. The difference of flow patterns also can cause variations in the rate of dispersion in the mixing tank.

Witryna14 kwi 2024 · Satjaritanun used a counter-rotating impeller to eliminate vortices and dead zones in the stirring tank, and this structure enhanced the shear pattern of the flow field and intensified the solid–liquid mixing effect, but the mechanical structure of the device was complex, resulting in a highly unstable stirring system.
