Note (General): The authors investigate the behavior of a bubble which bridges a gap in a cross section of a horizontal narrow divergent passage under the Eatrh's gravity condition(1G). In a narrow passage,inertia forces are known to be small compared with viscous forces. Also,gravity force is not dominant for bubble behavior in a horizontal narrow passage. In this sense,the bubble behavior in the passage is similar to that under a microgravity condition. It is important to understand the bubble behavior in relation to separating gas from a gas-liquid two-phase flow and controlling a gas liquid interface under a microgravity condition. A one-dimensional momentum equation for the bubble behavior was derived. The equation was converted into an ordinary differential equation with respect to the upstream interface and was solved. Analytical results were compared with experimental data. As a result,effects of gap size,bubble projected area,and divergent angle on the bubble behavior were explained qualitatively.
