Abstract
Some existing hydro-turbines, especially small turbines, have not been
extensively evaluated for their performance and possible upgrading. This may
be at least partially due to the fact that the traditional means of evaluation,
turbine testing, is quite expensive. The c.osts of design and evaluation can
now be substantially reduced by taking advantage of the recent development
of computational technology.
STS Hydropower Ltd. has contracted with the St. Anthony Falls
Hydraulic Laboratory of the University of Minnesota to conduct a preliminary
evaluation of the STS Series 60 Francis turbine using the recently developed
mathematical modeling program. After completing the simulation based on
the geometrical data initially furnished by STS Hydropower, new geometrical
data were received and recalculations requested. The new geometry differs
from the old one in that the trailing end has been lengthened and the edge
sharpened and also a more streamlined leading edge given. Also, calculations
of two flow conditions was requested: maximum efficiency condition and
maximum output condition.
The work has now been completed and the results are described in this
report. Some recommendations for future work to improve the efficiency of
the turbine are also given.
