A comprehensive review of the studies of gas-liquid two-phase flow patterns and flow-
pattern maps at adiabatic and diabatic conditions is presented in this paper. Especially …

Publisher Summary This chapter reviews recently published research dealing with gas-
liquid two-phase flow in microchannels. Only microchannels with hydraulic diameters of the …

2092 data of two-phase flow pressure drop were collected from 18 published papers of
which the working fluids include R123, R134a, R22, R236ea, R245fa, R404a, R407C …

The calculation of frictional pressure drop for two-phase flow in pipes is required by a variety
of design practices. In the past six decades, many correlations for two-phase frictional …

PEM Fuel Cell Diagnostic Tools presents various tools for diagnosing PEM fuel cells and
stacks, including in situ and ex situ diagnostic tools, electrochemical techniques, and …

Two-phase flow pattern, pressure drop and void fraction in horizontal and inclined upward
air–water two-phase flow in a mini-gap annular channel are experimentally studied. A …

It is with great pleasure that I welcome this book by Professor Barry Azzopardi to the Series.
Multiphase flows, and in particular the gas-liquid flows which are the subject of this book, are …

The current paper presents new operational maps for several different multi-microchannel
evaporators, with and without any inlet restrictions (micro-orifices), for the two-phase flow of …

This paper presents a state of the art measurement and imaging systems used to determine
the Gas Void Fraction (GVF) of two-phase flow through annuli. Several research works were …

In this work, electrical capacitance tomography (ECT) and neural networks were used to
automatically identify two-phase flow patterns for refrigerant R-134a flowing in a horizontal …
