Publication - Experimental Study of Hydraulic and Thermal Behavior of an Ice Slurry in a Shell and Tube Heat Exchanger
CETC Number 2011-113 / 2012-02-01 Abstract Experiments were conducted in a shell and tube heat exchanger with an ethylene glycol ice slurry flowing in the tubes and hot water in the shell. Pressure loss in the tubes, inlet and outlet density for the ice slurry, in addition to inlet temperature, outlet temperature and mass flowrate for both fluids were measured. A transient study with a slurry flowrate of 10 kg/min and water flowrate of 5 kg/min revealed that, when the ice ...

Publication - Simulated Performance of a Solar Assisted Heat Pump Using Ice Slurry as a Latent Storage Material
CETC Number 2011-008 / 2011-09-16 Abstract A new solar assisted heat pump incorporating latent heat storage is proposed. Solar collectors are operated in series with a non-agitated ice storage tank, while a heat pump is used to transfer thermal energy from the ice tank to a warm water storage tank serving heating and domestic hot water demands. System performance is investigated in a high performance home in Montreal using the TRNSYS energy simulation program. Results show a ...

Publication - CFD Analysis of an Ejector for Cooling Applications
CETC Number 2011-045 / 2011-08-29 Abstract Vapour-jet ejectors have been used in cooling/refrigeration applications since the early 1900s. Recent efforts to reduce energy consumption by harnessing energy from low grade industrial waste heat or renewable energy sources have resulted in a renewed interest in this technology. This paper presents the results of computational fluid dynamics (CFD) simulations of a vapour-jet ejector operating with R245fa as the working fluid. The impact of ...
