| 摘 要： | 基于零兴波阻力理论,提出了一种非常规的S曲线形小水线面双体船(SWATH),其片体关于船中对称,单片体有一定艏向偏角.基于雷诺平均Navier-Stokes(RANS)方程黏流理论对设计进行求解验证,给出了设计的非常规SWATH静水中阻力性能.与常规带有鱼雷体状潜体的SWATH相比,设计的S形非常规SWATH不仅在低航速下(弗劳德数Fr=0.3)具有较低的阻力,在高速下(Fr≥0.8)也具有绝对的低阻优势.

| Abstract: | An unconventional small-waterplane-area-twin-hull(SWATH) ship was designed, whose twin hulls were slightly curved in an S-shape and arranged at a mean yaw angle but mirror symmetric to their common longitudinal center plane. Based on the “zero wave resistance” theory, a viscous flow theory which could solve the Reynolds-averaged Navier-Stokes (RANS) equations was used to study the resistance performance of the unconventional SWATH ship in calm water. In comparison with a benchmark conventional SWATH ship, which features a typical torpedo-shaped body, the simulation results prove the effectiveness of the S-shaped design. The unconventional SWATH ship has much less low-speed drag than its conventional SWATH counterpart and comparable total drag at high speeds. |
