Integral variables:  wetted surface area (S/L2), total resistance (CT), split into pressure (CP) and friction (CF) components, and form factor (k) 
Wave profile on hull
Longitudinal wave cut at y/L=0.172
Wave-elevation contours

global wave field

bow wave field

transom wave field
Axial velocity contours and cross-plane vectors at the propeller plane (x/L=0.435)
Axial velocity cut in the propeller plane (x/L=0.435) at z/L=-0.02
UD=0.4% along entire cut
(Assumed value)

Conventions

  • Coordinate system for comparisons is fixed to midship, undisturbed waterplane.

  • All quantities non-dimensionalized by density (r), ship speed (U) and length (L).

  • All CFD predicted force coefficients should be reported using the provided (geometry and conditions page) wetted surface area (SDWL).  Force coefficients defined as follows.
