Considering the relative velocity of the mixture (water + sediment) passing through a certain area of the impeller blade, a relative sliding distance (S) was estimated according to Eq.
to investigate the effect of the impeller blade angle and its shape on regenerative pump performance.
In the stator frame as well, the pressure field attached to the rotating impeller blade induces incoming flow field distortions [19].
Traditional centrifugal compressors with design capacities of 967kW (275 ton) and less also begin to suffer a degradation of full load efficiency due to the smaller impeller blade spacing which increases the flow friction losses (Stoecker and Jones 1982).
Moreover, the geometry shape of impeller blade has strong effect on pump performance, including vibrations.
The velocity streamlines of the impeller blade surface and the impeller inlet at 0.75[Q.sub.BEP] are shown in Figure 11.
The shroud has its inner contour shape in such a way to match the impeller blade tip from the inlet to the exit of the impeller.
For example, based on the research analysis, product development incorporating an impeller blade with an inwardly disposed bulge or bulge defined by d/d = T/D would establish propriety of the overall design that could maintain exclusivity on the market.
The distance from the surface of the liquid to the centreline of the impeller (submergence, S) was varied from the impeller blade height to half of the total liquid depth (0.01 m < S < 0.12 m).
