Inlet Gap Effect on Tonal Noise Generated from a Voluteless Centrifugal Fan
نویسندگان
چکیده
In this study, three voluteless centrifugal fans are compared for their aeroacoustic performances. The tonal noise is predicted by coupling the IDDES with Formulation 1A of Farassat. sources at blade passing frequency (BPF) identified. It found that related to fan inlet gap, which introduces higher velocity intensities and turbulent fluctuations interacting leading edge. By redesigning BPF reduced effectively.

Numerical study on the acoustic field of a centrifugal fan and the tonal noise sources
The widespread use of squirrel cage fans, especially in ventilation and home and industrial environments, has led to the formation of many research efforts to improve performance and reduce the sound produced by this type of fan. In the literature, the most important factor in generating sound in this category of fans is the confrontation between the rotor exit flow and the volute of the fan. I...
متن کاملVortex flows from centrifugal fan
A comprehensive work has been accomplished for the observation of flow details from a centrifugal fan inside an indoor unit of air conditioners. The present study is finding optimum flow paths in the system that supplies temperature-controlled air into the space human being. Fig. 1 shows the outlet grill of the system (left) and the flow details by PIV system (right) over the grill are objectiv...

abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
Session 1pEAa: Active and Passive Control of Fan Noise 1pEAa1. Active control of axial and centrifugal fan noise
Both axial and centrifugal fans are used to cool information technology (IT) equipment. These fans generate noise that can be annoying to their users, particularly the tonal noise that can be radiated. Work has focused on developing a method to attenuate the tonal noise associated with both of these types of fans. A compact system is used, whereby control sources are placed in close proximity t...
متن کاملThe influence of an adaptive nacelle inlet lip on fan noise propagation
The aeroacoustic performance of an adaptive inlet of a turbo-fan engine is numerically investigated in this paper. The sound intensity and directivity of the fan noise propagation to the far-field, and the sound level at lateral reference points are investigated. The investigation is performed for three Helmholtz numbers, with the influence of the mean flow included, for a single duct mode (8,1...
