Squirrel-cage fans (SCFs) are widely applied in heating, ventilation, and air conditioning
systems. Professionals in this field have made significant efforts to improve their design in …

Inspired by the swimming characteristics of carps in the C-shaped starting posture, the
bionic design of the blade is developed to improve the aerodynamic performance, reduce …

A numerical study of the aerodynamic and aeroacoustic behaviors of a backward curved
blade centrifugal fan was conducted under two important flow conditions: BEP and 1.3× …

Many previous researches have concentrated on the noise of backward-curved (BC) blades
and forward-curved (FC) multi-blade centrifugal fans. In this paper, an experimental study …

In this paper, the gap effects on the aerodynamics and tonal noise generation of voluteless
centrifugal fans are studied based on different gap geometries. The study is motivated by the …

Customer demands for quieter centrifugal fans in the industry have brought their noise to the
forefront. It is found that dipole sources on the surfaces of the rotating impeller and volute are …

This paper presents a multidisciplinary optimization procedure for enhancing the
aerodynamic and aeroacoustic performance of a forward-curved blade centrifugal fan for …

This research was inspired by the long-eared owl's ability to fly silently. For the first time in
this study, a wind turbine blade is designed to mimic the wing surface and the leading edge …

Abstract The hybrid CAA (Computational Aeroacoustics) method is used to numerical study
on the aerodynamic noise of a certain range hood. The CFD numerical calculation method …
