摘 要: | 舰艇在大风浪中航行,当航向已定时如何确定最大允许航速是航海界关注的课题。本文采用CFD(计算流体力学)方法和耐波性理论相结合的新模式,分别研究了浪增阻、风增阻及螺旋桨推力损失的计算方法,给出了比较精确的舰艇大风浪航行时的船体负载。在此基础上,运用船—机—桨理论,解决了最大允许航速(轮转速)的求解问题。

Abstract: | For ships navigating in heavy sea, when the direction is settled how to determine the maximum speed allowed is a subject of much concern in navigation circle. This page adopted a new model integrating CFD (Computational Fluid Dynamics) method with seakeeping theory, respectively researched the calculating method of wave wind resistance enhancement and propeller"s thrust loss, giving a relatively exact hull load of ship navigating in heavy sea. Based on this, using hull-engine- propeller theory, this paper solved the problem of calculating the maximum speed (wheel speed) allowed. |
