PARAMETRIC STUDY ON PERFORMANCE OF CROSS-FLOW TURBINE

In the present experimental study, the effect of blade number, nozzle entry are, and head on the performance characteristics of a cross-now turbine have been investigated. It has been observed that the efficien cy of the turbine increases with increase in blade number, nozzle entr y are, and head. The present investigation has also shown that there i s an optimum number of blades for a given nozzle entry are beyond whic h the performance of the cross-flow turbine deteriorates. It has also been shown that cross-now turbines at higher heads do not behave as pu re impulse turbines.
