Modelling of annular dispersed two-phase flow in vertical pipes

Experimental characterization of vertical gas–liquid pipe flow for annular and liquid loading conditions using dual Wire-Mesh Sensor

“…Vieira Asali et al [18]. Others, such as Ishi and Mishima [19] and Oliemans et al [20] have studied the entrainment process. Alves et al [21] developed a mechanistic model for annular flow in vertical pipes based on the separated flow approach.…”

“…Using the Kataoka and Ishii [23] correlation and previous experimental set-ups reported in literature [20], the test section was installed at a distance 17 m downstream from the inlet (L/d = 233) to promote fully developed two-phase flow. Similarly, in order to avoid disturbances to the flow, the WMS was placed 0.9 m upstream of a standard elbow (r/d = 1.5).…”

Void Fraction Prediction in Annular Two-Phase Flow Using an Algebraic Turbulence Model

“…In the derivation of the liquid film velocity profile in Cioncolini et al (2009a), the entrained liquid fraction was predicted with the Oliemans et al (1986) correlation. Correspondingly, the equation originally proposed for the turbulent eddy diffusivity was as follows:…”

Development of Next Generation Multiphase Pipe Flow Prediction Tools

“…The empirical correlation proposed by Oliemans et al (1986) may be used with modifications of the liquid physical properties (See in ).…”
