| Research Abstract |
1. Assessment of Experimental Data.
All the experimental data in the present study throughout the term of project were rearranged and were reassessed. Special cares were given to the relationship between temperature field and propagation of vibration within the micro-structural suspensions and slurries of micro-powders.
2. Simulations and analysis.
The simulations were performed continuously in order to store the simulation data which should be analyzed before the total report.
3. Total assessment and analysis of the research results and report
Total discussions were carried out on all the experimental data on the relationship between temperature field and propagation of vibration within the micro-structural suspensions and slurries of micro-powders in the present study throughout the term of project. And the final report in which the heat transfer mechanism were clarified and the effective method for active control of heat transport within a micro-slurries was made
Micro structural slurries such as suspensions were suffered a change of inner structure due to its inner share stress by a small vibration. The change is affected by a variety of conditions such as micro-particles in a suspension and inner connection condition among the particles. Furthermore, it is also found that the change of inner structure of such materials also suffers the change of its thermal transport properties. The results of the present study gives a possibility of controlling heat transfer using a small vibration of materials.
