CALCULATION OF SPLITTING VANES AND INNER FLOW ANALYSIS FOR
CENTRIFUGAL PUMP IMPELLER*
Abstract:
The calculation method for vane numbers is obtained on the intention that it should have no back flow area in the flow passage of centrifugal passage. Then a criterion that the design of splitting vanes of centrifugal compound impeller should ensure that the back flow area ratio be the minimum is proposed. On the basis of the criterion, the slippery theory is used as one of CFD methods to analyze the inner flow field of the impeller of various kinds of splitting vanes design, therefore, the optimized design of splitting vanes is obtained and which agrees with that of some testing results.
