基于CFD的实船阻力快速预估方法

摘要

介绍了一种实船阻力快速预报的方法，通过数值计算得到形状因子（1+k）以及兴波阻力系数，结合实船试航积累的模型-实船相关系数，快速预报船舶的阻力性能。对两型不同类型的船舶应用该方法预报其设计工况附近的阻力性能，预报结果得到实船试航结果的验证，表明该方法具有值得期待的工程应用前景。%This paper introduces a full scale ship resistance performance prediction method. By this method, the form factor (1+k) and wave making resistance coefficient are obtained numerically, then the full scale ship resistance performance can be quickly predicted according to the model scale-full scale correlation coefficient accumulated through sea trials. The resistance performances of two ship types near the design condition should be predicted using this method. The prediction results are validated through sea trial which demonstrate that this method has a good prospect in engineering applications.
