- Additional information
- DC casting is an important industrial process and ultrasonic treatment is recognised as a means of refining microstructure and reducing alloying element segregation. Modelling is used here to understand and optimise the process, using a custom-built multi-physics model. The model, at the leading edge of the field, couples sound waves, flow and cavitation dynamics to predict acoustic streaming in the sump, and its effects on sump profile and mushy zone thickness. Physical experiments conducted in parallel, provide validation. A product of continuing collaborative research EPSRC (EP/R011001/1) between Greenwich and Brunel and Constellium, the work is attracting strong industrial interest.
