A method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow

Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...

Visualization and Analysis of Swirling Flow in Bubble Eliminator

Bubbles and the dissolved gases in liquids greatly influence the performance of fluid power systems, coating solutions, plants in the food industry and so on. Therefore, it is important to eliminate bubbles in liquids and to prevent degradation of the quality the system performance as well as to avoid possible damage of the components. These problems are often viewed with the knowledge of the d...

Rheology of bubble-bearing magmas

The rheology of bubble-bearing suspensions is investigated through a series of three-dimensional boundary integral calculations in which the effects of bubble deformation, volume fraction, and shear rate are considered. The behaviour of bubbles in viscous flows is characterized by the capillary number, Ca, the ratio of viscous shear stresses that promote deformation to surface tension stresses ...
