Regarding the effect on the skin friction resistance of the wavy roughness like a painted surface on the hull surface, the law for the sandy rough surface cannot be applied, and it is impossible to estimate the quantity of the frictional resistance c

The air lubrication method, which mixes millimeter bubbles into the flow around the hull and reduces frictional resistance, is expected to have a large energy saving effect among a number of marine energy saving technologies. Concerning the frictiona

Air entrainment and bubble generation by a hydrofoil bubble generator for ship drag reduction have been investigated using a small high-speed channel tunnel with the gap of 20 mm in National Maritime Research Institute (NMRI). A hydrofoil (NACA4412,

Friction drag and characteristic of bubbles in horizontal water channel are investigated at bulk liquid velocity Um = 1 ∼ 5 m/s (Reynolds number Rem = 16,000 ∼ 120,000 (based on the channel height)) and mean void fraction α = 0.5, 1, 2 %. Firstl

Since added resistance in waves is a key parameter for prediction of ship performance in actual seas, it should be measured with sufficient accuracy. In general, the measurand obtained in a model test contains unavoidable error, which results from th
