The influence of operational parameters (as the chamber volume under plate with the orifice, liquid viscosity, liquid height and orifice length) will be highlighted in a present study. The increase of the chamber volume results in the emergence of zones with multiple states for the bubble size. This corresponds to the multiple states of bubbling period. The increase of the liquid viscosity, a liquid height and an orifice length is more complex. The surface properties of the orifice and the ratio of the orifice diameter to the capillary length have to be considered in explanation of observed behaviors..
