Numerical methods

Question 1

Strip Method

Answer 1

• Applied for sleder ship bodies
• requires the calculation of hydrodynamic mass, damping and wave forces on each section in regular waves
• Calculations are simplified by looking at the sections as infinite cylinders so that only a 2D flow has to be solved (x,z)
• Flow is considered to be frictionless and irrotational
• All non-linearity due to body motion or the wave field are neglected
• The motion of the ship section or of the incident (reflected waves) waves are considered to be harmonic
