A numerical optimization on the vibroacoustics of a centrifugal fan volute
A numerical optimization is presented to reduce the vibration and noise of a centrifugal fan volute. Minimal vibration was considered as the aim of the optimization, and the calculation of sound field induced by the vibration of the volute was only based on the final results of the optimization. After the three-dimensional unsteady flow simulation of a centrifugal fan, the parametric finite ele...
متن کاملTrue Value Estimation of Centrifugal Fan Vibration Data Based on Fusion Method
Poor information means incomplete and insufficient information, such as unknown probability distributions and trends. In this case, many statistical methods may become ineffective. So a fusion method based on the information poor theory is proposed. The fusion method contains five methods, three concepts, and one rule. The five methods include the rolling mean method, the membership function me...
متن کاملExperimental investigation on sound of a centrifugal blower and fluctuating pressure on its volute
The Research has shown that the primary sound source in centrifugal turbomachines is the blade passing frequency noise, which is caused by due to impac rotor exit flow with the volute and the wild pressure fluctuations. In this paper, a centrifugal blower with forward facing blades has been selected and the sound created by it in the output channel has been investigated in different operating c...
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...
متن کاملEffect of impeller geometry on performance characteristics of centrifugal compressor
Centrifugal Compressors play an essential role in oil, gas and petrochemical industries. Their extensive usage is due to their smooth operation and high reliability compared to other other compressor types. One of the main characteristics of these turbomachines is their performance curve, which is an important criterion for selecting the appropriate compressor for a desired working condition. I...
