Modelling of the isothermal melt flow due to rotating magnetic fields in crystal growth

Effect of the Fluid Convection Driven by a Rotating Magnetic Field on the Solidification of a PbSn Alloy

“…At the beginning of the activities a rotating magnetic field (RMF) was chosen to generate a forced convection in a cylindrical melt column because for this case a number of theoretical and experimental data about the flow pattern are already available [6][7][8][9][10], although for isothermal conditions, only.…”

Computer Modelling of Bulk Crystal Growth

“…A general review of magnetohydrodynamics in materials processing is given by Davidson [52]. Some examples include use of magnetic fields to suppress convection in microgravity Bridgman experiments [53][54][55], to control instability in Czochralski growth [24], and to promote mixing in melt-growth systems [56,57]. A typical model consists of the equations in Table 3.2 with the Lorentz body force included in the momentum balance:…”

Velocity Measurement Techniques for Liquid Metal Flows

“…Similar to thermal sensors, PDPs have been thoroughly employed for the measurement of mean velocities down to their resolution of around 1 mm/s [25,26], and to determine turbulence characteristics of fast flows [27,28]. An advantage of PDPs is the utilization in those cases where a strong magnetic field is intrinsic to the problem.…”
