MEASUREMENT OF DYNAMIC SURFACE TENSION IN BUBBLING SYSTEMS
The static and dynamic surface tension was measured for aqueous solutions of eleven surface-active agents for the purpose of studying the effect of surface tension upon boiling heat transfer. The surfactants were chosen from the Tween, Aerosol, and Hyonic series. Dynamic surface tension, at T = 90 deg C, was investigated by observing the volume and frequency for air bubbles forming from a submerged orifice. Static surface tension, at T = 100 deg C, was measured using a duNouy tensiometer. In all cases, the dynamic surface tension for solutions of these surface active agents was less than the value for pure water, greater than the static value for the same concentration, and was a smoothly decreasing function of concentration.
