The modelling of oxide film entrainment in casting systems using computational modelling

“…The size of the particles added to the flow was defined by assuming that the defects were thin films with a layer of entrapped air between the two oxides. From past work oxide films have been commonly measured at 0.5 -2.0 mm in length [31,[35][36][37][38] although both much larger and smaller films have been identified in published works [39][40]. Based upon the published data a maximum and minimum square defect size was defined wherein the maximum and minimum side lengths of a square defect were 2 and 0.5 mm respectively, and the thickness of the defect one tenth of the square edge length.…”
