Abstract
Liquid atomization has many applications such as car fuel injector, heat dissipation, coating, medical use, etc. The most common way in atomization is to exploit high frequency and high vibration amplitudes of piezoelectric devices. This paper investigates the effectiveness of a giant magnetostrictive transducer for atomizing liquids. Effect of vibration amplitudes on output parameters such as atomization size and output Dubai have been investigated so as the frequency response of the transducer when plunged into the water. Droplet size particles have been measured through high speed camera. Results show that using giant magnetostrictive transducer leads to uniformity that is considered a key factor in many applications. Results demonstrates that sonic transducers based on giant magnetostrictive material can be profitably used as liquid atomizers.
