Résumé

The paper reports an experimental study of non-boiling air-water flows in a narrow conduit (diameter 1.95 mm). Results are presented for pressure drop characteristics and for local heat transfer coefficients over a wide range of gas superficial velocity, liquid superficial velocity, and wall heat flux. For a given liquid flow rate, the data exhibit sudden changes in pressure drop and, to a lesser extent, in heat transfer characteristics as the gas flow is increased. These events are believed to correspond to flow transitions, from bubbly, to intermittent slug, to annular flow.
