The magnetic fluid surface profile determination in magnetic-fluid sealing device at the given pressure difference

摘要

On a basis of the physical fields FEM approach to position and form determination of magnetic fluid in magnetic-fluid sealing device at given pressure difference is considered. The magnetic fluid form locating process reduces to optimization search procedure of such finite elements net profile at which in all boundary surface elements of magnetic fluid the required magnetic induction value is provided. This value is determined by pressure difference and temperature. The magnetic fluid configuration locating results are given.
