Advanced impeller design: Anti-ragging impeller, ARI2
Chemical Engineering Research and Design, 2013Abstract The waste water treatment plant anoxic denitrification process employs agitated vessels which contain process fluids contaminated with fibrous, rag-like materials that have a tendency to collect on impeller blades and adversely affect mixing performance. The existing Philadelphia Mixing Solutions Ltd.

AMC-made Impeller-type Buckwheat Dehuller and Optimization of Impeller Speed
Bhutanese Journal of Agriculture, 2022The outer hull or husk of buckwheat (Fagopyrum esculentum Moench.) kernel comprises about 20-30% of the weight of the buckwheat grain. Since it is inedible it should be removed before processing into flour. While imported and expensive dehulling machines are available in Bhutan, to reduce cost and gain wider adoption by farmers and perform the ...

VIBRATION SPECTRUM OF QUANTUM IMPELLERS
International Journal of Modern Physics B, 2010For the first time, we construct a quantum impeller model, then we adopt the invariant eigen-operator (IEO) method to derive its vibration spectrum. Vibration spectrum of the quantum impeller composed of two types of laminae is also deduced. It seems to us that IEO method greatly simplifies the derivation.

Individual impeller flooding in aerated vessel stirred by multiple-Rushton impellers
Chemical Engineering Journal, 2006The paper presents flooding detection in the dispersion of air into water in a stirred vessel equipped with a multiple-turbine impeller. All experiments were performed in a pilot-size mixing vessel using single, dual and triple Rushton turbine impellers. Deionized water and compressed air were used as a working fluid.

Journal of Turbomachinery, 1988
The results of extensive laser measurements carried out in the blade passages of a newly designed backswept impeller are presented and discussed. Noticeable distortions of the throughflow patterns and a distinct swirling flow character were found inside the rotor.

Effect of Impeller Speed Perturbation in a Rushton Impeller Stirred Tank
Journal of Fluids Engineering, 2012Flow inside an unbaffled Rushton-impeller stirred tank reactor (STR) is perturbed using a time dependent impeller rotational speed. Large eddy simulation (LES) revealed that the perturbation increased the width of impeller jet compared to the constant rotational speed cases.

Abstract After operating for six months, a pump impeller (of nickel-containing cast iron) showed considerable corrosion. Cross sections showed substantial penetration of the wall thickness without loss of material. The observed supercooled structure implied low strength but would not affect corrosion resistance.

Comparison of Rotordynamic Fluid Forces Between Closed Impeller and Open Impeller
Volume 1: Symposia, Parts A and B, 2012In the design of rocket turbopump with high energy density, rotordynamics considerations are very important to stabilize the motion of the shaft. Rotordynamic instabilities generated by rotordynamic fluid forces are often reported. It is recognized that the forces affect the whirling motion of the rotor, and induce the self-excited vibration.

A blower for fluidized particulates has a housing with an inlet in one wall. The housing defines a chamber which also has an outlet. A rotatably mounted shaft projects into the interior of the chamber. Circumferentially spaced around and projecting laterally from the shaft are a plurality of blades which individually have a shape selected to ...
