| Outline of Final Research Achievements |
A viscoelastic fluid which is a certain kind of surfactant solution has the function to reduce drastically flow resistance in turbulent flow. However, heat transfer is largely suppressed in the drag reduced flow. On the other hand, there are many studies on heat transfer enhancement of fluid flow by adding nano-particles. In this study, the fundamental study on the improvement of the suppressed heat transfer in the drag reduced flow of the viscoelastic fluid by adding nano-particles. Such fluid which is the viscoelastic fluid by mixed with nano-particles is called as viscoelastic nanofluid in this study. The result shows that the suppressed heat transfer is slightly improved by addition of nanoparticles compared to the drag reduced viscoelastic fluid flow. The viscoelastic nanofluid in which contains the fiber shape nano-particles having large heat conductivity is more effective for achievement of improvement of heat transfer in drag reduced flow.
