Bio-Inspired Blade Cascades: Numerical Predictions Versus Experimental Measurements [PDF]

Biomimetics
This work presents a numerical–experimental validation of aeroacoustic predictions for bio-inspired leading edge serrated blade cascades. Transient simulations were carried out on a four-blade cascade using several turbulence modeling strategies commonly

Bio-Inspired Blade Serrations: A Review on Owl-Based Strategies for Aeroacoustic Noise Mitigation [PDF]

Biomimetics
The increasing deployment of wind energy has brought renewed attention to aeroacoustic noise generated by wind turbine blades, where broadband noise is primarily associated with vortex shedding at the trailing edge (TE) and leading edge (LE) of airfoils.

Numerical Analysis and Experimental Research of Multi-blade Centrifugal Fan based on Leading-edge Serrated Blade

Zhileng xuebao, 2019
A serrated leading-edge blade for a multi-blade fan of an air conditioner is designed. The main objective is to reduce the vortex near the blade, thus reducing the flow loss and aerodynamic noise of the flow field of the multi-blade fan.

Development of low-noise and large-air flow rate bionic serrated blades for multi-blade centrifugal fans in heat pump dryers

Case Studies in Thermal Engineering
A heat pump dryer usually adopts a centrifugal fan with multi-blades for generating large flow rate of air, but faces the problem of high aerodynamic noise. The application of bionic serrated blades instead of straight-edged blades in fans is a promising

Aerodynamic performance of blade based on owl trailingedge serrated design

Journal of Physics: Conference Series
Abstract As the noise reduction induced by owl trailing-edge serrated design of wind turbine blade during operation has gradually become the industrial consensus, the corresponding effect of the aerodynamic performance on blade has still not been investigated systematically.
