2412 Effect of Fan Loading on Tip Leakage Vortex in a Semi-open Axial Fan
Details
In order to clarify the behavior of tip leakage vortex in a semi-open axial fan, the experimental investigation was carried out using the Laser Doppler Velocimetery. Velocity vector maps were obtained at the blade rotor tip region and the pattern including tip leakage vortex were clarified As a result, it is found that the trace of tip leakage vortex changes as the fan loading changes. Furthermore, it is also found that the trace of tip leakage vortex changes as the tip clearance size changes.
