EXPERIMENTAL STUDY ON CHARACTERISTICS OF NANOFLUID FOR LOW-TEMPERATURE PHASE CHANGE COOL STORAGE

摘要：

The TiO2-BaCl2-H2O nanofluid with 1.13％ volume fraction of TiO2, which has the dimension of 20nm, was prepared by supersonic oscillator with hydrophilic dispersant. BaCl2 solution and TiO2-BaCl2-H2O nanofluid were tested by the experiments of freezing. The experimental results show that nanofluid has remarkably lower subcooling degree than BaCl2 solution, and the cool storage capacity of the nanofluid is larger than that of BaCl2 solution. Comparing with BaCl2 solution,the heat transfer characteristic of the nanofluid is remarkably improved for the added nanoparticles.
