Bubble size distribution operating conditions, effect

The effect of the operation conditions on PSD in each state is different. Although the bubble size distribution in the operation has been expressed by various PSD functions, the PSD function that is most utilized is the normal PSD function. However, there is no physical background for applying the normal PSD function to the bubble size distribution. Additionally, when the bubble distribution is expressed by various PSD functions, it becomes difficult to discuss the relationship between the parameters in PSD and operation condition. This is one of the obstacles in the development of particle technology. 

The model was used to study the process sensitivity to the major unknown parameters the H2 bubble size (50-200 pm) and their departure angle (30-60°). The effect of cell orientation and electrolyte flow rate in the range of the pilot facility operating conditions (75-200 L.h 1) was also investigated. Process sensitivity is measured in term of cell voltage and gas fraction maximum and average values. Gaseous phase spatial distribution is also examined. Major simulation results are summarized in table 2.
