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 ...

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 ...

Injectable ice slurry for reducing pericardial adipose tissue

Lasers in Surgery and Medicine, 2023
AbstractObjectivesExcess pericardial adipose tissue (PAT) is associated with a higher risk of cardiovascular diseases. Currently, available methods for reducing PAT volume include weight loss through diet and exercise, weight loss with medications, and bariatric surgery.

The control of ice slurry systems: an overview

International Journal of Refrigeration, 2005
This article outlines some typical control strategies for the basic components of an ice slurry system. From this review it became apparent that the control of terminal units is not fundamentally different from the control of classical single-phase secondary cooling systems, except from the fact that it must be based on the use of local pumps and the ...

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 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 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.

Control of Ice Crystal Growth by Different Surfactants in Ice Slurries

Applied Mechanics and Materials, 2014
Ice crystal growth problem have attracted special attention due to in heat transfer deterioration and pump power consumption increasing, by adding very small amount of suitable additives can control the ice crystal growth. This paper investigates ice crystal growth in isothermal condition when adding four different additives, and then calculate the ...

Modeling transport phenomena of ice slurry in an ice forming unit

International Journal of Refrigeration, 2016
In this article, multiphase convective and solidification transport phenomena of ice slurry is investigated by developing a one-domain macroscopic model to simulate its formation in a rectangular ice forming unit. Convection, sedimentation, interfacial drag, permeability, remelting and viscosity variations are incorporated into this model through the ...

Ice fraction error calculation in ice slurries

2001
L'utilisation des fluides frigoporteurs diphasiques est freinée par le manque de fiabilité des générateurs de coulis de glace et par la précision de la technique de mesure de concentration en glace. L'article présente une méthode simplificatrice de calcul de concentration en glace d'un coulis en se basant sur la méthode calorimétrique.
