Observations are reported on the two-phase bubble flow of air rising through a stationary water phase. Distinctly different results have been measured for tap water and for distilled water. The difference in these results is attributed to the presence of an extremely small quantity of an unknown sur

โฆ Synopsis
The nse speeds and top jet drop ejectton heights of nsmg and burstmg bubbles m water are measured as a function of bubble age Equivalent spherical diameters range from 0 08~ d <O 12.5 cm Various types of relatively surfactant-free water are used Both nse speeds and top Jet drop ejecnon heights decrease with bubble age This IS due to adsorption of surface-active materials on the bubble surface which Increases the rigldlty of the surface and decreases Its surface free energy In general, termmal values of rise speed and ejecnon height are not reached at the same bubble age The ages at wluch these terminal values are reached are characterIstically greater for larger bubbles m a given water sample These ages are also characterIstically greater for bubbles of a gven sze as the concentration of surface-active material m the water decreases

Bursting bubbles are thought to be the dominant cause of cell death in sparged animal or insect cell cultures. Cells that die during the bubble burst can come from three sources: cells suspended near the bubble; cells trapped in the bubble lamella; and cells that attached to the rising bubble. This
