Abstract
Levitation of liquid bodies against gravity is a contactless confinement process ap- propriate for manufacturing very pure materials. A variety of levitation techniques have been de- veloped over the last few decades, such as aero- dynamic, acoustic, electrostatic, microwave, and electromagnetic levitations. More recently, a new generation of novel techniques, essentially combinations of the established primary tech- niques, has been successfully introduced. Exam- ples are acoustic-electric, aerodynamic-acoustic and acoustic-electromagnetic. Thepurposeofthis series of papers in three parts, Bakhtiyarov and Siginer (2007a,b), is to review the advances in electromagnetic levitation (EML) since its intro- duction as a containerless melting technique, and a tool for the determination of the thermophysical properties of molten metals under both terrestrial and microgravity conditions.
