本文基于船舶在流场中航行的理论及潮流场对船舶作用的原理,对给定航线的潮流状况结合主机油耗作数值计算,提出了航行船舶利用潮流能节约能源的初步研完成果。 虽然潮流能的品位低于潮汐能,但它用于航行船舶节能有显著实效,在开发利用海洋能方面有其实际意义。 Based on the theory of ship’s sailing in the flow field and the principle of the tide field acting on the ship, this paper presents a numerical calculation of tidal current conditions and main engine fuel consumption for a given route. Although tidal current energy is lower than tidal energy, it has significant effect on energy conservation of sailing ships and has practical significance in developing and utilizing ocean energy.
