  impeller
First, the internal flow field of each impeller was calculated.
      
Second, the concurrent working point of each impeller was approximately estimated.
      
Finally, a calculation was performed considering the influence on each impeller.
      
Although both impellers had the same blade cross-section, one impeller had a two-dimensional blade, while the other had a leaned blade.
      
The average cavitation performance of each impeller was satisfactorily predicted by the numerical simulations.

Cavitation in semi-open centrifugal impellers for a miniature pump
      
Cavitation in miniature pumps was investigated experimentally for two semi-open centrifugal impellers.
      
Although both impellers had the same blade cross-section, one impeller had a two-dimensional blade, while the other had a leaned blade.
      
Three impellers (I, II, III) having same outer diameter, but different radius ratio and blade angles were employed for the investigation.
      
The total pressure developed by the impellers in each case is found to be maximum at a circumferential position of around 270°.

  impellor
Antibiotic production by the mutant strain, U190, however, appeared more shear sensitive than the parent culture FCRF 341 with maximum antibiotic titer being inversely related to impellor tip velocity, Tv.
      
Cases of physical interest involving off-clamped beams include wobbling rotors, impellor blades, and turbine blades.
      
The impellor model described above predicts dynamo action for sufficiently-strong forcing.
      


Based on the analysis of the working process of the vane ofvane-type oxygen-adding machine under water, the paper puts forward the theorythat under stable operations, the moment of resistant force acted on the vane bythe water is mainly composed of two parts: the coherent moment of resistantforce and the working moment of resistant force.

Based on the analysis of the working process of the vane ofvane-type oxygen-adding machine under water, the paper puts forward the theorythat under stable operations, the moment of resistant force acted on the vane bythe water is mainly composed of two parts: the coherent moment of resistantforce and the working moment of resistant force. The paper also sets up thetheoretical formulas for calculating the total moment of resistant force andpower exhaustion. These theoretical formulas are varified through the calculation of power ex-haustion of machines with various power through and they are of great practicalvalue in improving the design, decreasing the power exhaustion and reducingthe cost of the machine.

All experiments were carried out in geometrically similar vessels with diameters of 0. 287m,0. 495m and 1. 100m respectively. Bubble size distributions were measured by a dual electric conductivity probe in upper,lower circulation regions and impeller region in the tanks. The distributions of local bubble size in the tanks have been studied,and a better understanding of the mechanism of gas-liquid dispersion process is given. The effects of operationg conditions(such as agitated power consumption per unit liquid volume and gas superficial velocity) and the scale of the vessels on the bubble size have been studied,and the correlation equations for the bubble size in the upper and impeller regions were proposed. The scale-up rule of gas-liquid stirred vessels was dicussed,then some proper scale-up methods were proposed. The experimental results are of value in the design and scale-up of aerated stirred vessels.
