Liquid surface flow velocity. The velocity of rotating Sn at the edge of the target as function of q ref for different stages during the oscillation cycle a. The rotational flow during phase II is seen to increase with q ref. A small decrease in rotation speed occurs during a single shielding cycle at heat fluxes of 12.2 and 16 MW m−2. A radial component to the flow velocity, only observed during phase III, is shown in b. The data points represent the average of ~10 independent measurements at equal phases within different vapour shielding cycles. The error bars represent the s.d. of these data sets
