Outline of Final Research Achievements

Nanofluid is paid particular attention as the promising method to enhance critical heat flux in boiling heat transfer. It is considered that the CHF enhancement is mainly caused by the modification of surface properties such as the wettability and roughness due to the formation of nanoparticle layer on the heated surface. However, since adhesion of the nanoparticle layer is not firm, peeling of the layer often occurs during boiling. In the present work, peeling test was conducted to measure quantitatively the adhesion strength of the nanoparticle layer formed on the heated surface. It was found that the total mass and the adhesion strength of the nanoparticle layer were dependent strongly on the particle material. The CHF enhancement ratio by nanoparticle layer tended to decrease with an increase in the peeling ratio. It may be interesting to note that the boiling heat transfer was improved whilst CHF was deteriorated with the increase of the loss of nanoparticles.
