Computational Analysis of Ultrasonic Treatment of Melt for Effective Dispersion of Reinforcement Particles

7 pagesPublished: August 5, 2017

Abstract

In many engineering fluids, micro or nano solid particles are introduced to enhance their effect. Introduction of nanoparticles in radiator coolant enhance its efficiency and introduction of micro/nano reinforcement particles in liquid metals enhance its mechanical properties. In most of the applications, de-agglomeration of particle clusters and uniform dispersion of particles is desirable to enhance the process. Ultrasonic streaming and cavitation can help in achieving the desirable output. In this work, the ultrasonic streaming and dispersion of micro SiC particles in water and liquid Aluminium were numerically simulated (using COMSOL multiphysics) and compared. Parameters selected for carrying out the investigations were power of ultrasonic generator and diameter (tip) of probe. Results obtained for water were validated by experimental results. The medium viscosity and density are the key factors influencing ultrasonic streaming and cavitation. The results provide reference for the ultrasonic treatment of melts for making Metal Matrix Composites (MMCs).

Keyphrases: Acoustic pressure, cavitation, Metal Matrix Composites, Probe tip diameter, Ultrasonic power, Ultrasonic stirring
