| Abstract: | An investigation and analysis on non-Newtonian rheologic characteristic and heat transfer performance for a new O/W-type emulsion in a circular tube before and after phase changing, results obtained indicated that the emulsion, as a new cold-storage material, had some advantages in the convective heat transfer performance. The variations of mains rheology parameters of the emulsion with the concentration and temperature of the emulsion, as well as the convective heat transfer performance of the emulsion in the tube were measured and discussed. The study has provided the necessary basis for design of the new practical cold-storage equipment. |
| Keywords: | phase-change emulsion cold-storage rheologic characteristic heat transfer performance |
