Comparision of Inner Surface(Water Surface)An Experiment on Inner Shapes(Water Side)of Heat Transfer Pipes for Flon Use and its Applications (Observation of Vortex Patterns by Flow Visualization of Stream Lines)

摘要

Authors are earring out Ocean Thermal Energy Conversion, in this process we experiedced that heat transfer pipes are the most probleme. Our heat pipes are the ones improved for home refrigeration use. They have very excellent quality, but we knew that there is a margin for improvement. This was unbalance between heat transfer quality of flon surface and that of water surface. We made a observatdon on stole vortex patterns of water surface by flow visualization method. After the observation, we knew that stole vortexes much concern to heat transfer. In this paper, mainly, vortex patterns were tested, but a suitable shape of water surface which can make a strong stole vortex was clarified.
