| Abstract | A standard water tunnel flow visualization technique was used to demonstrate some of the flow phenomena near a strongly cambered flexible blade from a typical commercially produced automotive cooling fan.
The study identified basic flow problems that could degrade the aerodynamic performance of the cooling fan and give rise to increases in noise level in the broad band frequency range and at multiples of shaft frequency.
The observations are discussed in the light of the actual operational environment and the limitations of the test method used.
Proposals are made towards modifying the present blading design in order to reduce or overcome the flow problems observed during the water tunnel test. |
