Abstract
In this paper, it is shown that wetting properties crucially control the possibility of forming ordered patterns in two-phase flows of immiscible fluids in microchannels. Ordered patterns are obtained when one phase completely wets the walls, while disordered patterns are unavoidably produced when wetting is partial.
