摘要
在所设计的绿色无动力船的基础上,对动力板截面进行了修型,并数值模拟了水流速为5m/s、船以各级速度行驶时的受力情况;结果表明,经平底修型后增大了翼型的弯度,明显改善了压力面分布,增大了升力系数以及船以各级速度行驶时对应的升阻组合系数。
Based on the previously designed green powerless ship,the dynamic board cross-section was modified.After that,at the hypothetical condition of the velocity of water flow is 5m/s,we simulated the flow of the process on which the boat traffic at 1～5 m /s all rates in a Numerical way.The comparison between prototype and modified type of the airfoil showed that the modification increased the bending of the airfoil and improved the face of pressure remarkably.As a result,the lift coefficient and the corresponding combination of resistance and lift coefficient were significantly increased,and the performance of the ship was improved.
