| Abstract |
This report describes the work performed to compute new wind coefficients for the Tripoli estuary container vessel at a draft of 3.5 meter as used in the simulator of Flanders Hydraulics Research. An approximation of the ship geometry as used in the simulator is created. Computations are performed using the Computational Fluid Dynamics (CFD) software suite FINE/Marine. For thirteen relative wind directions (with 15 degrees increment), meshes are generated and the setup of the computations are done. The new set of coefficients (10 degrees increment) is computed using a cubic spline interpolation. The wind angle of the resulting force is computed for the original and new coefficient sets and it is found that for the new set, the wind angle varies in smoother way than the original coefficient set. Almost one month of cluster time was required to compute the new coefficients. This is too much to do this on a regular basis. |
