计算流体力学方法在船舶领域的实用性研究

通过CFD（计算流体力学）方法对船舶领域两个典型的工程实例进行了数值计算和流场模拟，模拟的流场与船池试验的流场很吻合。数值计算结果和试验值比较，在特定n范围内相对误差在6．6％以内，满足工程要求。表明数值方法在船舶航速预报方面具有一定的工程实用性，以CFD计算结果为依据光顺流场流线优化船舶阻力性能的可行性也得到工程实例证明。

Study on the Practicability of Computational Fluid Dynamics for Marine Applications

This study carries out numerical flow field simulations using the CFD （Computational Fluid Dynamics） method for two typical engineering application cases, the resulting flow fields agree well with the model experiments. The comparison of numerical and experimental results show that the relative errors are within 6.6% for a certain range of Fr values, which satisfies the engineering application requirements. Therefore, the numerical method has some engineering practicability for ship speed prediction, also the feasibility of using CFD results to smooth the flow field stream lines for the purpose of optimizing ship resistance performance is validated by these practical engineering cases.
