The demand in micro-air vehicles is increasing as well as their potential missions. Either for
discretion in military operations or noise pollution in civilian use, noise reduction of micro-air …

The yokeless and segmented armature axial flux machine is considered an excellent
topology for electric vehicles application. However, its performance is severely limited by the …

Fans are commonly used to cool electric motors. They can be mounted directly on the
electric motor shaft providing a simple and inexpensive cooling system. The fan sizing is …

A multidisciplinary optimization to simultaneously enhance the aerodynamic and
aeroacoustic performance of an axial-flow fan was performed. Flow analysis through the …

The intake of dust and dirt contained outside the air into the motor while driving causes the
maintenance of dismantling and clean-up operation once every three years. Moreover …

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 …

Bladeless fan is a novel fan type that has no observable impeller, usually used for domestic
applications. Numerical investigation of a Bladeless fan via Finite Volume Method was …

A trash rack is used to obstruct dirt in a flow. As it is on the outside of the hull of a ship, such
flow-induced noise cannot be ignored. This paper focuses on a hydrodynamic noise study of …

Purpose Wind power is the one of best natural resources to meet the demands of electricity
in India. In this regard, one of engineering college in Visakhapatnam has procured wind …

This study aims to minimize the noise generated by automobile cooling fans. Fan blade
structures with ridged surfaces based on bio-inspired principles are 3D printed and used to …
