基于计算流体力学方法的水线面大开口工程船阻力性能分析

Study on Resistance Performance of Working Ship with Notches Based on CFD

运用计算流体力学(CFD)方法对工程船由船体水线面大开口所引起的船体阻力性能变化进行了分析.通过对某水线面大开口型工程船系列模型的黏性绕流进行数值模拟,得到在低航速下水线面大开口型船舶船艏开口纵向和横向尺寸变化,船艉开口纵向和横向尺寸变化以及艏艉开口相互作用对船体阻力性能的影响,为改善此类船型的船体阻力性能提供了参考依据.

Variance of ship resistance caused by notches in working ship was studied based on CFD method. By numerically simulating the viscous flow around a series of working ship models with notches, the effects of the variation of notch size in bow in longitudinal and transverse direction, the variation of notch size in stern in longitudinal and transverse direction and the interaction of the notches in bow and stern on ship resistance performance at low speed were obtained. Basis for improving the resistance performance of this kind vessel was provided.
