Levitator for Containerless Processing
Objects are levitated by aerodynamic forces in an apparatus originally developed for space research but just as effective on Earth. New levitator is orientation-independent. Also works equally as well whether or not gravity is present. Apparatus supports a sphere by aerodynamic forces from gas flowing through convergent/divergent section. Concentric inner tube is moved along axis of cylindrical housing.
