In order to clarify the effect of rotor inlet geometry of half-ducted propeller fan on performance and velocity fields at rotor outlet, the experimental investigation was carried out using a hotwire anemometer.
Three types of inlet geometry were tested.
The first type is the one that the rotor blade tip is fully covered by a casing.
The second is that the front one-third part of blade tip is opened and the rest is covered.
The third is that the front two-thirds are opened and the rest is covered.
Fan test and internal flow measurement at rotor outlet were conducted about three types of inlet geometry.
At the internal flow measurement, a single slant hotwire probe was used and a periodical multisampling technique was adopted to obtain the three-dimensional velocity distributions.
From the results of fan test, the pressure-rise characteristic drops at high flowrate region and the stall point shifts to high flowrate region, when the opened area of blade tip increases.
From the results of velocity distributions at rotor outlet, the region with high axial velocity moves to radial inwards, the circumferential velocity near blade tip becomes high, and the flow field turns to radial outward, when the opened area increases.
