| Outline of Final Research Achievements |
In the previous studies, we obtained the result that the critical heat flux was significantly improved by the coupling of the nanofluid and the honeycomb porous body, so the mechanism was experimentally investigated. As a result, in addition to the improvement effect of the honeycomb porous body, it was clarified that the liquid was supplied from the porous body to the cell by the nanoparticle layer, the size of the dry spot was reduced by the nanoparticle layer, and the wickability was improved.

| Academic Significance and Societal Importance of the Research Achievements |
冷却の限界が、伝熱面の静的なぬれ性でなく、動的なぬれ性にも強く依存することが、ハニカム多孔質体においても明らかにされたことは、今後さらなる冷却性能を向上させる重要な指針になると考えられる。
