Parametric Study of Centrifugal Fan Performance: Experiments and Numerical Simulation

In this paper, effect of geometric parameters of a centrifugal fan with backwardand forward-curved blades has been investigated. Centrifugal fans are used for enhancing the heat dissipation from the IC engine surfaces. In the process, the fan consumes power generated from the engine. As a first step, an experimental setup was developed and prototypes of fans were made to carry out measurements ...

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...

Vortex 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...

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...
