Focusing Properties of Bicylindrical Acoustic Lenses
Acoustic lens Bicylindrical lens Focusing
2009/8/19
This theoretical report concerns the focusing of a plane progressive acoustic wave by a bicylindrically-curved lens. It was assumed that the lens was made of polymethylmethacrylate (PMMA) and was subm...
Influence of Surface Properties of Coatings to Frictional Resistance
Frictional Drag Reduction Self-Polishing Paint Water-Repellent Paint Sand Roughness Scale Effect
2009/5/12
In order to clarify correlation between properties of coating on ship hull surfaces and frictional resistance, experimental studies were carried out. A rotating cylinder type dynamometer was newly dev...
