Abstract
The development of the theory of turbulence has made a breakthrough in the application of drag reduction technology on ships, which contributes to energy saving and environmental protection. When a ship is sailing, it has to overcome resistance. Total resistance includes frictional resistance, wave-making resistance, and viscous pressure resistance, in which frictional resistance acts as the main resistance for low-speed ships, and for high-speed ships, the main resistance is wave-making resistance. This paper reviews the ship drag reduction technology by giving a brief introduction to drag reduction methods using grooves, bulbous bows, bubbles, hydrofoils, wall vibration, and high-polymer additive respectively, as well as their principles.
