The shear instability occuring at the interface between a slow water layer and a fast air stream is a complex phenomenon driven by momentum and viscosity differences across the interface, velocity gradients, as well as by injector geometries. Simulating such an instability in the conditions of experiments is numerically challenging and few studies exist in the literature. This work aims at filling a part of this gap by presenting a study of the convergence between two-dimensional simulations, linear theory, and experiments, in regimes where the instability is triggered by confinement, i.e., the finite thicknesses of the gas and liquid streams. Very good agreement between the three approaches is obtained. Moreover, using simulations and lin...
