Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2004 One of the essential differences in the design of bubble pressure tensiometers consists in the geometry of the measuring capillaries. To reach extremely short adsorption times of milliseconds and below, the so-called deadtime of the capillaries must be of the order of some 10 ms.

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998 Abstract The dynamic surface tension of Triton X-100 solutions was measured using the maximum bubble pressure method (MBPM). The data obtained depended on the geometry and material of the capillaries employed. It is shown that reliable results are obtained with short capillaries of hydrophobic internal surfaces.

Surface tension measurement of oil/refrigerant mixture by maximum bubble pressure method
International Journal of Refrigeration, 2017Abstract Lubrication oil used in refrigerant compressors forms oil mist in the compressor shell. Some of the oil mist is discharged into a refrigeration cycle with refrigerant and causes degradation of heat transfer in heat exchangers. Since the generation of the oil mist is related to the Weber number, it is necessary to measure the surface tension ...

The measurement of dynamic surface tension by the maximum bubble pressure method
Colloid & Polymer Science, 1994The principle of maximum pressure in a bubble for measurements of dynamic surface tension is realized in a fully automatically operating apparatus. The set-up yields data in the time interval from 1 ms up to several seconds and can be temperature controlled from 5° to 80°C.

Dynamic surface tension of micellar solutions studied by the maximum bubble pressure method [PDF]
Colloid & Polymer Science, 1994 A theoretical model for the dynamic surface tension of an air bubble expanding in surfactant solution is proposed. The model accounts for the effect of convection on the surfactant diffusion and the effect of expansion of the bubble surface during the adsorption of surfactant molecules.

Unusual Characteristics of the Maximum Bubble Pressure Method Using a Teflon Capillary
Journal of Colloid and Interface Science, 1994Abstract The maximum bubble pressure method has been used recently in a continuous-bubbling mode to measure the dynamic surface tension of surfactant solutions at varying bubble frequencies. A modification of this method, which utilizes a syringe pump supplying gas at controlled rates, has been developed to examine bubble growth by providing an ...

Dynamic Surface Tension of Micellar Triton X-100 Solutions by the Maximum-Bubble-Pressure Method
Journal of Colloid and Interface Science, 1994Abstract The dynamic maximum-bubble-pressure method was used to measure the dynamic surface tension of Triton X-100 solutions (at the CMC and at concentrations above the CMC). Measurements were performed at 30.0, 40.0, 50.0, and 60.0°C. The results at 30.0°C are in excellent agreement with the data obtained through other methods (oscillating jet and ...
