    Summary
    Experimental and numerical studies are performed to characterise the dynamics of isolated confined air bubbles in laminar fully developed liquid flows within channels of diameters d = 0.5mm and d = 1mm. Water and glycerol are used as the continuous liquid phase, and therefore, a large range of flow capillary numbers 10−4
