Abstract

Abstract: Axial fans are found to be one of the major sources of the noise in modern devices such as PCs, HVAC systems, turbo engines and etc. Lot of researches were going on for decades to reduce this unwanted noise. Researchers have found that application of leading-edge serrations will lead to reduction of noise from the bio-inspired study on the wings of barn-owl. This project involves in the study of effect of Aerodynamic performance of axial fan in terms of pressure drop and aerodynamic efficiency using commercial CFD tool ANSYS FLUENT. Analysis have been carried out for a base model without serration and same model with serrations for various flow rates. The results are validated with the experimental results obtained by Krömer et al [1] and found to be in reasonably good agreement.
