Sintered disks, bubble formation

XVIII. Bubble Formation under Intermediate Conditions and at Sintered Disks. . 356... 

A sintered disk contains an extremely large number of potential sites for bubble formation, only a fraction of which form the operative sites. ... 

One of the major contributions from this group has been the development of a unified model, which could explain both bubble and drop formation through a single set of equations.This model has been tested for a variety of systems. It has been modified to take into account the complexities, drainage between bubbles, etc. New models have been developed for the prediction of drop and bubble sizes in complex situtations like sieve plates, sintered disks, etc. The model has been also extended to predict pneumatic atomisation, nucleate boiling, etc. 

Fig. 2.8 illustrates the Jackson cell14, by means of which accurate measurements within 0.1 mV can be made in a few minutes the sintered-glass disk permits the regular formation of minute H2 bubbles and the application of the two electrodes allows a check to be made of reproducible results.
