| 摘 要： | 船舶有效功率的准确预报对船舶的快速性和经济性有很大影响。本文采用Star-CCM+软件对某LPG运输船模型进行阻力计算,通过二因次法将其转化为实船阻力,然后预报实船的有效功率并与模型实验结果进行对比,验证数值计算结果的准确性。数值计算与模型实验2种方法所得结果的最大误差小于5%,证明基于Star-CCM+软件预报船舶有效功率的方法可行。

| Abstract: | The accurate prediction of the ship's effective power has a great impact on the ship's rapidity and economy.The resistance calculation of a LPG transport ship model was carried out by Star-CCM+software.It was converted into actual ship resistance by the second factor method,and then the effective power of the actual ship was predicted and compared with the model test results.Verify the accuracy of the numerical calculation results.The maximum error of the results obtained by numerical calculation and model experiment is less than 5%.It is proved that the method based on Star-CCM+software to predict the effective power of ships is feasible.The method used in this paper provides a certain reference for predicting the effective power of ships. |
