Abstract
Aerodynamic pressure pulsation generated by rotating fan blades was measured using a basic experimental device consisting of fan blades, a motor, and pressure gauges. The motor was installed on a high-stiffness block via load cells and the motor reaction forces were measured by load cells. On the other hand the aerodynamic pressure pulsation was also calculated using CFD simulation software, and based on those CFD results, motor reaction forces were also derived. Calculation results and experimental results were compared for both pressure pulsation and motor reaction forces. Finally, calculations were found to agree well with experimental results.
