Fig. 5: Reynolds number vs. temperature for flow in liquid Zr as a function of heater control voltage, as predicted by the laminar model.

Laminar flow is accessible for \(U_{\rm{ctr}}^{\rm{H}}\)  = 0.01 V for the entire temperature range and for \(U_{\rm{ctr}}^{\rm{H}}\) = 0.5 V at undercooling greater than 80 K.
