Parametric modeling was applied to the hull by using non-uniform rational basis spline (NURBS). The Rankine-source panel method was used to calculate the wave-making …
WebThe shell at the bow is also subject to panting from wave-impact loadings; this requires extra stiffeners, called panting stringers. It is customary in ship structures and ship components to limit the calculated stresses under the heaviest contemplated service loading to a certain fraction of the limiting stress for the material being used at which permanent … WebFormation of a bow wave also involves considerable production of vorticity. Similar to two-dimensional breakers, the primary origin of this vorticity is at the toe of the breaker. …
