✦ Synopsis

Potential flow theory is used to derive a theoretical model for gas bubble formation at an orifice exposed to liquid cross-flow in the plane wall of a duct. Model simulations show good correspondence with experimental data for single-bubble formation, consistent with primary bubble growth being controlled by liquid inertia forces. These forces are quantified in terms of radial velocity and acceleration of the gas-liquid interface. and relative velocitv between bubble and liquid. A simple "bubble pressure minimum" criterion yields reasonable prediction bf bubble size.

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
