N2 - The paper presents a numerical simulation of a stagnant (suspending) Taylor bubble fitted to the experimental conditions. The simulation is based on the unsteady model of k–ω SST (shear stress transport) turbulence. Simulation covers an analysis of gas-and-liquid flow parameters in the zones ahead of the bubble, after the bubble, and for the liquid film. The study demonstrates a compliance between the experiment results and simulation regarding the liquid film shear stress, the Taylor bubble nose shape, and the film thickness.
