Abstract Machine vision is widely used in the monitoring of froth flotation plants as a means
to assist control operators on the plant. While these systems have a mature ability to analyse …

This review discusses three types of soft matter and liquid molecular materials, namely
hydrogels, liquid crystals and gas bubbles in liquids, which are explored with an emergent …

In this work, a visualization experiment for rectangular channels was carried out to explore
gas–liquid two-phase flow characteristics. Typical flow patterns, including bubble, elastic …

The phenomenon of gas-liquid two-phase mixing inside rectangular channels has been
encountered in metallurgical and chemical industries. However, a large number of …

Passive acoustic methods are suitable for long-term seabed gas leak monitoring with high
accuracy under the condition of low cost and simple experimental equipment. However, the …

The aim of this work is to introduce a novel statistical technique for quantifying the
concentration field uniformity of the liquid-liquid mixing process within a micro-scale chaotic …

Valve leakage is a serious safety issue in petroleum and petrochemical production
processes. Traditional valve manufacturers examine valve leakage by manual visual …

Detection of air bubbles in fluidic channels plays a fundamental role in all that medical
equipment where liquids flow inside patients' blood vessels or bodies. In this work, we …

Collecting information on the flotation foam characteristics is important for controlling
flotation production conditions. Foam images acquired during coal slurry flotation are …
