Designers at Türk Elektrik have developed confidence in using FLUENT/UNS
for fan design, following a benchmark study recently completed. The FLUENT/UNS
model of the fan, used in the company's domestic vacuum cleaner products,
matched the experimental measurement of pressure rise through the fan
nearly exactly. A series of parametric models, testing new design options
over a range of operating conditions,
can now be conducted in order to gain insight into how flow separation,
stall, and flow reversal may impact design performance.
The centrifugal fan pictured here was used to validate
the accuracy of FLUENT/UNS for fan modeling. The CFD prediction of pressure
rise, equal to 21500 Pa, was within 2% of the experimental measurement
of 21000 Pa.
