Fig. 9: Convection in TiZrNi.

From: MHD surrogate model for convection in electromagnetically levitated molten metal droplets processed using the ISS-EML facility

Fig. 9

Maximum velocity (a) and maximum shear rate (b) vs. temperature as a function of heater control voltage, as predicted by the laminar model. Convection in the TiZrNi sample increases as temperature and heater voltage increase. umax and \(\dot \gamma _{{\mathrm{max}}}\) drop to zero as the sample undercools due to a large increase in viscosity.
