抵抗低減効果による流体輸送の省エネルギー技術の開発と普及

抄録

A commercially available drag-reducing additive, LSP-01, was developed in 1995. Since then, LSP-01 has been used at more than 180 sites in building air conditioning systems throughout Japan. The technique was adopted recently for air conditioning systems in skyscraper in the metropolitan area. In this paper, measurement of the velocity for a drag-reducing surfactant solution was carried out with the use of Particle Image Velocimetry (PIV) to provide a better understanding of the drag-reducing flows. The analogy between momentum and heat transfer for a surfactant solution is also discussed.
