    Abstract
  • Micro-encapsulated phase change material slurry （MEPCMS） was prepared using glycol solution as cold-based solution，and its physical properties were measured.Then，the thermodynamic properties of MEPCMS in tree microchannels were experimentally studied to reveal the influence of Reynolds number and mass concentration on the thermodynamic properties of MEPCMS.The results showed that the specific heat capacity of MEPCMS increased with the increase of microcapsule mass concentration and temperature，and the viscosity of MEPCMS increased with the increase of microcapsule mass fraction and the decrease of temperature.The convective heat transfer coefficient of MEPCMS increased with Reynolds number and mass concentration.When Reynolds number was 118，the convective heat transfer coefficients of MEPCMS at 1% and 3% mass fraction increased by 3.92% and 9.04%，respectively，compared with the base solution.The friction factor of MEPCMS decreased with the increase of Reynolds number and the decrease of mass concentration，but the friction factor of MEPCMS gradually approached the base solution with the increase of Reynolds number.
