Modelling the backwash process in micro filtration [PDF]

, 1991
Microfiltration separates fine solids from a liquid substrate, but requires a process to remove the accumulated solids from the filtering device. In this study, a backwash process was examined, in which a flow of high-pressure air in the direction ...

Stability of Air Nucleus in Liquid Water and Cavitation Inception on Marine Engineering

Polish Maritime Research, 2018
The micro air nucleus widely distributed in the ocean is a necessary condition for the cavitation of hydraulic machinery in seawater. In order to study the stability of air nucleus in seawater and cavitation inception, the computational domain of water ...

Polar Smectic Films

, 1998
We report on a new experimental procedure for forming and studying polar smectic liquid crystal films. A free standing smectic film is put in contact with a liquid drop, so that the film has one liquid crystal/liquid interface and one liquid crystal/air ...

Visualization of the formation process of slip flows by the air entrapment in microchannels

Nihon Kikai Gakkai ronbunshu, 2016
Processes of the air entrapment in microstructures fabricated on walls of rectangular microchannels were visualized by a high-speed camera. Effects of the geometry of the microstructures on the formation and the shape of the liquid-gas interface in the ...

Droplets on liquids and their long way into equilibrium [PDF]

, 2012
The morphological paths towards equilibrium droplets during the late stages of the dewetting process of a liquid film from a liquid substrate is investigated experimentally and theoretically.

Performance comparison of liquid, vapor, and liquid–vapor injection of single-screw compressor for an air-source heat pump

AIP Advances
Refrigerant injection techniques are usually proposed to improve the performance and reliability of compressors when a single-screw compressor applied to an air-source heat pump works at low temperatures in winter.

Compressible air flow through a collapsing liquid cavity

, 2010
We present a multiscale approach to simulate the impact of a solid object on a liquid surface: upon impact a thin liquid sheet is thrown upwards all around the rim of the impactor while in its wake a large surface cavity forms.

Optimal waste stream discharge temperature selection for dryer operations using thermo-economic assessment [PDF]

, 2012
A typical drying process that has liquid and gas discharge streams has been analysed and the impact of selecting various combinations of soft temperatures on heat recovery, utility targets, area targets, capital cost and total cost is reported.

The Density of Titanium(IV) Oxide Liquid [PDF]

, 1991
The density of TiO2 liquid in equilibrium with air has been measured at 1875° to 1925°C using an Ir double bob Archimedean method. The melt density data have been combined with data extrapolated from the CaSiO3─TiO2 join at 1600°C.

Air entrainment through free-surface cusps [PDF]

, 2000
In many industrial processes, such as pouring a liquid or coating a rotating cylinder, air bubbles are entrapped inside the liquid. We propose a novel mechanism for this phenomenon, based on the instability of cusp singularities that generically form on ...
