A comprehensive energy-saving sail (CES) was designed in order to promote energy saving and emission reduction of shipping. The CES can utilize wind for propulsion and power generation at the same time with its unique structure to collect wind energy. The feasibility of computational fluid dynamic (CFD) numerical model was verified by a case on arc wind sail, then this model was used to simulate the pressure field and velocity field around the sail. Results show that the outlet velocity of air tube vo and wind field velocity vi can be expressed as an equation vo≈1.31vi, therefore CES can effectively improve the conversion efficiency, and utilize wind for propulsion and turbine. The energy saving and emission reduction of Japanese coal cargo ship installed with CES were calculated based on the equation, the effect of energy saving and emission reduction on the voyage were verified.
