... by installing interceptors with different parameters. Zhen Qian (2018) found that installing interceptors on a trimaran extended the ship's virtual length, which in turn affected the distant wave pattern behind the stern. Additionally, interceptors could alter the hull pressure distribution, generate pitch...

... of nonlinearity on the resonant wave patterns is investigated. It is found that, if the steepness is large enough, the crestlines would curve and even split into two shorter crests. Its curvature extent is proportional to the primary waves' steepness and the propagation distance. By contrast, the nonresonant...

... Frp=1.03. For Fr<Frp, the maximum peak-peak amplitude Am increase with Fr and the wave patterns for such waves are dominated by stationary body-generated waves. For Frp<Fr<Frc, the maximum peak-peak amplitude Am decreases with Fr and the influence of wake-generated waves gradually increases...

...). With this instability, two dimensional(2D) waves of finite amplitude can be developed into 3D waves, forming complex wave patterns (Meiron, Saffman & Yuen, 1982; Yang, 1982). Surprisely, the three dimensional wake would turn into two dimensional one behind a rotationally oscillating circular cylinder when the amplitude...
