✦ Synopsis

THE LIQUID metals differ hydrodynamically from other liquids by their considerably higher surface tensions; because of this difference, the available correlations for velocity of rise of bubbles may not be applicable to liquid metals. In this communication the results are reported on a few measurements of velocity of argon bubles in mercury, and the results are compared with those for water.

EXPERIMENTAL METHOD AND RESULTS

The bubble velocities were measured with an ultrasonic pulse-echo instrument, the same as those used for detecting pores or cracks in metal products. Figure 1 shows the sketch DISYILLED WATER

The rising velocity of an isolated bubble in a "two-dimensional" air-fluidised bed has been measured and found to be wel1 described by the relation, ub= 15'9Abf cm/sec, where Ab is the area of the bubble measured in cm\*. This predicts a smaller rising velocity than the corresponding @avies and Tayl

## POPE [l] and Sorrrnwaa~ [2], commenting upon the foamiug properties of sea-water, suggested the possible presence of surface-active substances to account for these properties, though they were unable to detect such materials. Sruxx [8] has shown that long-chain fatty acids (e.g. caproic and cap
