How does the blockage effect of a short duct affect the propeller noise?5 answersThe blockage effect of a short duct can significantly benefit noise control for propellers. Installing the propeller at the symmetric plane of the duct can achieve the most noise reduction. The blockage effect can also affect the cavitation pattern on the blade surface, especially when cavitation is intense. The Glauert formula can satisfactorily correct thrust, torque, and hydrodynamic efficiency even in moderate cavitation, but it is not recommended when cavitation is intense. The presence of an incoming airflow can modify the noise radiation of a ducted propeller, both in the frequency and spatial domain. The ground effect near the ducted propeller can lead to a high-pressure zone that blocks the jet flow through the outlet of the duct, affecting the aerodynamic forces and powers of both the duct and propeller. The ground effect should be considered in the process of aerodynamic and conceptual design for ducted propellers in near ground hover state.
