Hh. Stapelberg et D. Mewes, THE PRESSURE LOSS AND SLUG FREQUENCY OF LIQUID-LIQUID-GAS SLUG FLOW IN HORIZONTAL PIPES, International journal of multiphase flow, 20(2), 1994, pp. 285-303
Experiments were performed which took into account the influence of a
second immiscible liquid upon gas-liquid slug flow. Well-known models
for the prediction of the slug frequency and pressure loss, as well as
the flow pattern maps of two-phase flow, were extended for this speci
al kind of multiphase flow.
