- In the manufacture of metal matrix nanocomposites, the biggest challenge relates to the uniform dispersion of nanoparticles, which tend to cluster together becoming defects in the final product. A first-principles approach is followed in a bespoke CFD-DEM code explaining the fundamental forces between the nano/micro particles and quantifying their response to external pressure pulses. The CFD-DEM code was coupled to a pioneering acoustic cavitation model used to simulate MMNC production in crucibles (EU FP7 ExoMet) with cavitating bubbles as the pulse source. The software is currently used in EPSRC EP/P034411/1, “Contactless Ultrasonic Processing for Liquid Metals”.
