- The use of sound resonance to vibrate liquid metal melts forms the basis of the new contactless sonotrode technology. Accurate soundfield calculation in a real crucible is however non-trivial, due to the various materials comprising the process setup and the presence of gas in the melt generated during cavitation. Competing time-domain and frequency domain simulations are compared to guide experiments, leading to successful grain refinement of aluminium, tested with and without commercial grain refiners. The work is part of EPSRC projects (EP/P034411/1, EP/R000239/1, EP/R002037/1).
