Mechanistic models for multiphase flow calculations can improve our ability to predict pressure drop and holdup in pipes, especially in situations that cannot easily be modelled in a I;laboratory and for which reliable empirical correlations are not available. In this paper, a new mechanistic model, applicable to all pipe geometries and fluid properties, is presented. New empirical correlations are proposed for liquid/wall and liquid/gas interfacial friction in stratified flow, for the liquid fraction entrained and the interfacial friction in annular-mist flow, and for the distribution coefficient used in the determination of holdup in intermittent flow.
