Review on flow and heat transfer properties of CO2 hydrate slurry as secondary refrigerant
摘要
Abstract
The recent development of flow and heat transfer research of CO2 hydrate slurry was reviewed as a secondary refrigerant. In the aspect of flow research, five flow patterns(Newtonian flow, Pseudo-plastic flow, Dilatant flow, Bingham plastic flow and Herschel-Bulkley flow) were introduced. It shows that CO2 hydrate slurry is a kind of non-Newtonian liquid with small apparent viscosity indicating excellent flow properties. With regard to heat transfer aspect, the calculation method of hydrate slurry overall heat transfer coefficient in the plate heat exchanger was presented, and CO2 hydrate slurry has excellent heat transfer properties with a convective heat transfer coefficient of 3658W/(m2·K). Moreover, heat transfer properties can be affected by crystal diameter and distribution, flow velocity, solid content and tube dimensions. In conclusion, CO2 hydrate slurry has good prospects in air conditioning application with good flow and heat transfer properties. Finally, the future research priorities on CO2 hydrate slurry were discussed and summarized.关键词
