The effects of various factors on the volumes and shapes of bubbles formed at a single orifice submerged in non-Newtonian liquids, such as physical properties of liquids, gas chamber volume, orifice dtimeter and gas flow rate were studied. To clarify the bubble formation mechanism, the bubble volume

number of authors have on the basis of experiments determined that pressure and gas density can have an influence on bubble formation size. Usually this influence is attributed to the gas momentum force, generated by gas flowing into the bubble during its formation. In this article the theoretical b
A new model for the prediction of volumes of bubbles generated from a single orifice in twophase gas-liquid systems has been developed based on a rigorous bubble closure mechanism. The interaction between the primary bubble and subsequent bubbles formed at the orifice has been incorporated into the
## Abstract **Summary:** NonβNewtonian fluid behavior has significant influence on quantities in chemical engineering like power input, mixing time, heat transfer etc. In the laminar flow region, the concept of effective viscosity by Metzner and Otto is well established. In the transition region be
