INFLUENCE OF AXIAL MISALIGNMENT TO A TMF DRIVEN FLOW
摘要
The travelling magnetic field (short: TMF) is a commonly used alternating magnetic field, which is applied e.g. to tailor heat and mass transport during crystal growth processes. Numerical studies usually assume ideal configurations such as a perfectly adjusted magnetic field. However, an ideal setup can be hardly realized in "real processes". In the present work, we study the sensitivity of a TMF driven fluid flow within a cylindrical configuration, when a small offset is introduced between the container's axis and that one of the magnetic field. It will be shown, that already a small misalignment affects the flow seriously. Especially in supercritical regimes the mean flow as well as the turbulent structures changes considerably, whereas the variations in the laminar regime correlate approx-imately with the magnitude of the axes' shift.
