摘要：Performance of axial fan is found to reduce drastically when instab ility is encountered during its operation. Performance of an axial fan is severely impaired by many factors mostly related to system instabilities due to rotating stall and surge phenomenon experienced during its operation. The present work involves measur ing the sound spectrum measurements in ducted axial fan under stall condition s at frequency range from 0 Hz to 5 00 Hz. Objective of the experiment is to measure the frequency domain signal and study the sound Ch aracteristics in ducted axial fan by using sp ectrum analyser. Different types of FFT signals have been measured under stall condition s for the frequency range of 0 Hz to 5 00 Hz with respect to rotor speed and different graphs are plotted for ducted axial fan
