Title: Analysis of Dynamic Characteristics of Circular Arc Sail for Wind Assist Ship Propulsion
Abstract: Wind assistance in ship propulsion is one of the important applications of renewable energy.This paper analyzes the pressure distribution on the windward surface of a circular arc sail,lift force and resistance created by the sail,effects of the camber ratio on sail dynamic characteristics and the dynamic characteristics of abreast combination sails using mathematical model of ke turbulence flow equations and the CFD software of Fluent.The pressure on the windward surface of the circular arc sail decreases along wind direction.A proper increase in camber ratio of the sail may be beneficial for ship windward sailing.Properly adjusting the attack angle of the sail will increase the driving force. There exists interaction among abreast combination sails.The results of numerical analysis coincide with test results in wind tunnel,which can be the guidance for the development of sails for wind assist propulsion.
