Optimisation of ingot casting wheel design using SPH simulations

Smoothed Particle Hydrodynamics (SPH): an Overview and Recent Developments

“…• underwater explosions and water mitigation [125,143,[247][248][249]255], • elastic and/or plastic flow [52,114,[257][258][259], • fracture of brittle solids [260], • metal forming and high pressure die casting [68,[261][262][263][264][265][266][267][268][269][270], • magneto-hydrodynamics and magnetic field simulation [271][272][273][274][275][276][277][278][279][280][281][282], • problems with fluid-solid interactions [176,196,210,[283][284][285][286][287][288], and • many other problems like blood flow [289][290][291][292], traffic flow …”

Modelling of metal flow and oxidation during furnace emptying using smoothed particle hydrodynamics

“…Gomme et al (2006) used SPH for predicting shear stress levels in biological fluids passing through a lobe pump. Prakash et al (2007) used SPH to model flow of molten aluminium through an ingot wheel system consisting of a rotating wheel and translating ingots. A brief summary of the SPH method is presented here.…”

“…Previous work in simulating the wheel system for aluminium re-melt ingot casting presented in Prakash et al (2007) is an example demonstrating this advantage of the SPH method.…”

“…Cleary et al (2003) presents the early work carried out in this project. Prakash et al (2007) provides more comprehensive details and a summary of the wheel design optimisation process. The experimental configuration used had a 500 kg crucible furnace emptying metal from a small drop (420 mm) into a launder feeding the casting wheel (Fig.…”

Novel applications of smoothed particle hydrodynamics (SPH) in metal forming

“…The formation and tracking of surface oxide has been effectively demonstrated in ingot casting simulations [11] with SPH and relies in its in-built history tracking capability. • Coarse grain structure: a final forging may contain coarse grains if the finishing temperature is too high or strain is too low [8].…”
