| Outline of Final Research Achievements |
In the present study, wall contamination on a heat transfer surface is considered a process of fine particle accumulation on the heat transfer surface. The final scope of the present study is to build a physical model where contamination accumulated on the solid-liquid interface affects the interfacial thermal resistance. An experiment is performed to evaluate the interfacial thermal resistance with and without nanoparticle accumulation. In addition, molecular dynamics simulations are performed to numerically investigate the interfacial thermal resistance. Experimental results are consistent with results of the molecular dynamics simulations. Based on those results, deeper understanding of the interfacial thermal resistance with the contamination particles on the interface is obtained.
