Sentence examples for impeller radius from inspiring English sources
When the gap between the impeller and the volute tongue is less than 20% of the impeller radius, the amplitude of pressure fluctuation noticeably decreases as the gap increases.
The second set of PIV measurements is on a curved θ z plane whose radial location is just outside the impeller blade tip radius.
The impeller-induced flow at the blade tip radius is modeled by using sliding mesh method.
At the inner radius interface of the basket, the vertical blade impeller induces a rather homogeneous velocity profile, but the pitched blade impeller imposes a high velocity at the plane of symmetry.
In addition, the 'spottiness' of the normalized kinetic energy along a radius as the trailing vortex moved away from each impeller can be identified, which is not shown from time-averaged data.
A novel experimental method (the "steady cone radius method", SCRM) is proposed to determine experimentally the minimum impeller speed at which solids are completely suspended.
Gas flow rate measurements at higher impeller speeds indicated that the pressure driving force was a function of the detached bubble radius, and providing this dependence was known, the model could be used to predict the rate of gas induction.
The impeller back plate of the rotor experiences a strong pressure fluctuation, which is maxima at the impeller outer radius for all operating point, but higher pressure values at the surge point.
The bulk flow velocities, averaged over 360° of impeller rotation, showed an axial jet with a ring vortex encompassing two-thirds of the vessel height, swirl velocity proportional to radius beneath the impeller as in solid body rotation and counter-rotating vortices behind the baffles.
The radius never changes".
