Effects of rotating magnetic fields on thermocapillary flow: Comparison of the infinite and the Φ1–Φ2 models

Effects of rotating magnetic fields on thermocapillary flow in a floating half-zone

“…The mesh sensitivity and the convergence criteria are described in detail in Ref. [30]. The applied magnetic field strength B 0 of RMF is 7 mT and 14 mT, and the rotating frequency l of RMF is 50 Hz.…”

Numerical simulation of Cz crystal growth in rotating magnetic field with crystal and crucible rotations

“…e r and e y are the radial and angular position, respectively. In the computation of Lorentz forces, the infinite model is widely adopted in the literature [5,11,12], which ignores the effects of the convection on the electric current and the magnetic field. Therefore, the components of the Lorentz force in our model may be written in the following form: f r ¼ 0, f z ¼ 0 and f y ¼ ðs m B 2 0 or=2Þ.…”

“…Compared to a static magnetic field, rotating magnetic field (RMF) requires much lower magnetic induction for effective convection control, and therefore requires less energy consumption. In addition, RMF can eliminate the virtual asymmetry of heating, reduce radial segregation in the melt, control of the shape of the liquid-solid interface, stabilize the melt motion, and increase the rate of mass transport [5]. Thus, RMF has become increasingly interesting for convection control in crystal growth.…”

Application of magnetism in tissue regeneration: recent progress and future prospects

“…A RMF refers to a MF in which the magnetic induction vector rotates in space with a certain regularity. RMF can also be generated by a variety of methods, such as by rotating a permanent magnet, the simulation models of which are typically RMF infinite and RMF φ-φ models [ 56 , 57 ]. Under the action of the RMF, the magnetic material will be subjected to regular rotational force along the direction of the MF compared with the SMF.…”
