In situ hydrodynamics

Additional research on the prediction of flow patterns is a necessity, for until detailed stability criteria are developed for the transition from one flow pattern to another, there is no alternative to the empirical flow pattern charts. Some progress in theoretically defining the transition from stratified to wavy or slug flow has been made by Russell and Etchells (R3). Inaccuracy and uncertainty in flow pattern prediction makes estimation of the in situ hydrodynamic quantities and the rate of heat transfer a difficult task. 

It has been seen that the other in situ hydrodynamic cells discussed above, the channel electrode cell and the tube electrode cell, both exhibit EPR signal (S) characteristics dependent upon the ratio However, in the case of the wall-jet electrode under steady state conditions, in which the entire cell downstream of the working electrode is filled with radicals, the rate of loss of radicals from the cell is proportional to Vf, while the rate of their formation is proportional to i, thereby anticipating...
