ABSTRACT

It is proposed to determine the velocity and shape of a two-dimensional long bubble moving in an inclined channel or in a vertical tube. In this test case a liquid moves with a uniform velocity within the tube. The results may be compared to analytical or numerical solutions and to experimental data.
