Outline of Final Research Achievements

We tried to control the drag-reducing effect of the mixture of nonionic surfactant solution and photo-rheological fluid by using the UV radiation. We clarified the effect of UV irradiation on friction factor versus Reynolds number, and then the effects of solution temperature and the molar ratio of surfactant and photo-reactive additives. Moreover, we proposed the screening method for the drag-reducing property, which is based on the detachment process of the droplet in the transient elongational flow.
