Microscale Adiabatic Gas-Liquid Annular Two-Phase Flow: Analytical Model Description, Void Fraction, and Pressure Gradient Predictions

John Richard Thome, Lorenzo Consolini, Andrea Cioncolini, Chin Lee Ong

The study is devoted to the modeling of microscale adiabatic gas-liquid annular two-phase flow. The turbulent diffusion of momentum in the annular liquid film is assumed to be governed by the conditions near the channel wall, in analogy with single-phase t ...

Recent Developments in Flow Boiling and Two-Phase Flow in Small Channels and Microchannels

John Richard Thome, Andrea Cioncolini

Microscale two-phase flow is at present one of the hottest topics of heat transfer research, both in academia and in the industry. The miniaturization of two-phase flow systems, which has led to numerous experimental and theoretical challenges not yet comp ...

Algebraic turbulence modeling in adiabatic gas–liquid annular two-phase flow

John Richard Thome, Andrea Cioncolini

The study considers algebraic turbulence modeling in adiabatic gas-liquid annular two-phase flow. After reviewing the existing literature, two new algebraic turbulence models are proposed for both the liquid film and the droplet laden gas core of annular t ...

Unified macro-to-microscale method to predict two-phase frictional pressure drops of annular flows

John Richard Thome, Andrea Cioncolini

The study considers the prediction of pressure gradients in adiabatic gas-liquid annular two-phase flow in the macro-to-microscale range Twenty-four empirical correlations have been tested against an experimental data bank drawn together in this study cont ...

Subcooled and saturated water flow boiling pressure drop in small diameter helical coils at low pressure

Andrea Cioncolini

Experimental pressure drop results on boiling water flow through three helical coils of tube inner diameter of 4.03 mm and 4.98 mm and coil diameter to tube diameter ratio of 26.1, 64.1 and 93.3 are presented. Both subcooled and saturated flow boiling are ...
