Developments in many modern applications are encountering rapid escalation in heat
dissipation, coupled with a need to decrease the size of thermal management hardware …

Column separation refers to the breaking of liquid columns in fully filled pipelines. This may
occur in a water-hammer event when the pressure in a pipeline drops to the vapor pressure …

High-speed video and infrared thermometry were used to obtain time-and space-resolved
information on bubble nucleation and heat transfer in pool boiling of water. The bubble …

This article offers an overview of the instrumentation techniques developed for multiphase
flow analysis either in gas/liquid or in gas/liquid/solid reactors. To characterise properly such …

A set of closures for two-fluid modelling of adiabatic bubbly flows has been defined as
baseline model, which provides a common basis for further improvement and development …

We introduce a new wire-mesh sensor based on capacitance (permittivity) measurements.
The sensor can be used to measure transient phase fraction distributions in a flow cross …

A wire-mesh sensor with a time resolution of 1.2 kHz was used to measure bubble size
distributions in a gas-liquid flow. It is designed for a pipe of 51.2 mm diameter and consists …

Multiphase flow is a commonly seen transient and complex dynamic system in many
industrial processes. The phase fraction and velocity are two of the most important …

This paper presents a robust image processing technique for bubbly flow measurement over
a wide range of void fractions. The proposed algorithm combines geometrical, optical and …

Measurements of the cross-sectional distribution of the gas fraction and bubble size
distributions were conducted in a vertical pipe with an inner diameter of 51.2 mm and a …
