Laparoscopic Ice Slurry Coolant for Renal Hypothermia

Journal of Urology, 2007
We assessed the safety and efficacy of microparticulate ice slurry for laparoscopic hypothermia during renal ischemia in a single kidney porcine model.A total of 18 farm pigs were randomized to 3 groups of 6 each. All groups underwent initial right laparoscopic nephrectomy, followed by 1 of 3 procedures on the left kidney.

Ice fraction measurement of ice slurries through electromagnetic attenuation

International Journal of Refrigeration, 2014
Abstract Ice pigging is a process used by many industries for pipe cleaning and product recovery. Ice slurries, used to form an ice pig, are generated using an aqueous solution of water and a freezing point depressant, typically salt (NaCl) at 5% salinity.

Ice slurry generation involving moving parts

International Journal of Refrigeration, 2005
Efficient ice slurry generation systems continuously produce ice crystals of desired size offering high cooling rates without any wall freeze-up. Although several ice slurry generation technologies have been and are being developed, currently only the scraped surface and supercooling type have been widely used in commercial applications.

Energy conservation in ice slurry applications

Applied Thermal Engineering, 2013
Abstract Significant improvements in coefficient of performance (COP) can be made when the evaporating temperature of a vapour compression cycle is raised. Producing the ice slurries used in cooling applications and ice pigging by crushing blocks of ice made from pure water and mixing the particles with a solution of freezing point depressant (FPD ...

Ice slurry production using supercooling phenomenon

International Journal of Refrigeration, 2010
The studied ice slurry production consists in generating ice from a flow of supercooled water or aqueous solution. After leaving the evaporator of the refrigerating plant, the supercooled flow is physically disturbed in order to generate ice crystals.

Ultrasonic detection of slurry ice flows

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2005
Experimental work has been carried out to investigate the use of ultrasound in the detection of slurry ice flows within pipes. The work sets out the basis for a novel device that is both portable and adaptable to retrofitting onto existing pipelines. This method of noninvasive pipeline interrogation has applications within many parts of the chemical ...

Ice Slurry Thermal Energy Storage System

10th AIAA/ASME Joint Thermophysics and Heat Transfer Conference, 2010
A laboratory scale ice slurry thermal energy storage (TES) system for high power device cooling is demonstrated. The TES rate is greater than 60 kW in a 30 s discharge period. The primary water flow as the heat source with a designed flow rate of 1.44 kg/s (or greater) and a temperature of 20 to 30°C is cooled down to a desired temperature by the TES ...

Thermodynamic Nonequilibrium in Ice-Slurry Systems

Journal of Thermophysics and Heat Transfer, 2009
Compared with classical secondary refrigerant loops that continuously supply cold energy, ice-slurry systems rely on the use of storage tanks designed to store and supply the cold energy on demand; thus cutting off cooling peak demands. To reliably operate an ice-slurry cooling system, it is very important to know the ice-loading fraction within the ...

The fluid dynamics of ice slurry

International Journal of Refrigeration, 2005
A review of research work of fluid dynamics of fine-crystalline ice slurry is presented. Different rheological models which are applied are presented. Numerous models for the friction factor, obtained by empirical and semi-empirical approximation, are discussed.

Ice slurries characteristics

1998
Cette communication présente les caractéristiques thermophysiques d'un mélange binaire d'eau et éthanol. On compare les propriétés thermiques du mélange monophasique et diphasique. On présente sur un exemple simple le comportement thermohydraulique d'un mélange sous forme monophasique et diphasique en écoulement dans un tube.
