Abstract

The application of ice slurry as secondary refrigerant is limited up to
now. The main objective of this research is to study the thermal and
hydro behavior of an ice slurry system during different operational
processes of the ice slurry such as: Generation Process inside different
types of ice slurry generators, Transportation process inside straight
circular pipes, Melting process in heat exchanger and inside straight
circular pipes, and Thermal storage process inside the thermal storage
tank. Other objective is to compare the super-cooled water jet type as
ice slurry generator with competitive scraped surface traditional ice
slurry generator. A final objective is to study the thermal behavior and
the hydro behavior of produced ice slurry in other ice slurry system
components. A test rig with all the necessary measuring
instrumentation has been set up to carry out the different kinds of the
experiments performed. The generation process focus on the influence
of ice slurry generator parameters on the prevention of ice scaling in
tested ice slurry generators at different conditions. The transportation
process of ice slurry in circular straight pipes is thoroughly studied and
investigated. Pressure drops, and friction factors, and flow coefficients
across flow meters are evaluated. The melting process of ice slurry in
artificial heat exchanger is thoroughly investigated in the present work.
Heat transfer coefficients and superheating were measured during ice
slurry melting process experiments in a tube-in-tube heat transfer
electrical heating coil. Historical pictures were taken during the thermal
storage experiments demonstrate the developing of the ice layers inside
the thermal storage tank of cylindrical shape. A comparative CFD Study for two different type of ice slurry generators is presented and
demonstrated using commercial CFD Package. A comparison between the experimental work results, and the CFD results obtained, was performed to validate the tested numerical model and the tested ice slurry generator of super-cooled water jet type. The conclusions from the different experiments are summarized to give the integral conclusions.
