Atomisation rate and gas/liquid interactions in a pipe and a venturi: Influence of the physical properties of the liquid film

► Description of the annular two phase flows in pipe with respect to the liquid viscosity. ► Behaviour of these flow when submitted to a shearing and pressure gradient. ► Measurement of the velocity of the interfacial waves with respect to the flow condition and liquid properties. ► Characterisation of the atomisation of the annular liquid film in the convergent of a venturi metre. ► Relationship between the atomisation rate and the liquid film characteristics (film thickness, wave amplitude).
