WitrynaThe flow pattern may be analyzed in terms of its three components of motion; radial flow, in a direction perpendicular to the impeller shaft; longitu-dinal or axial flow, in a direction parallel to the shaft; and tangential flow, in which the liquid follows a circular path around the shaft. WitrynaFlow pattern; Impeller type; Power number; Number of impellers; The dispersed phase volume fraction; Gas-gas mixing. 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. hilary\\u0027s necklace classic

"Witrynatype and also either curved or flat blade type. Radial flow impeller without disc does not produce mixing in a proper radial direction since pressure gradient occurs on either side of the rotating impellers. Radial impellers with disk have higher power consumption and gave uniform radial flow patterns. Fig. 1 Radial flow impellers IV. " - Impeller flow pattern
