Holtrop-Mennen Model & ITTC Formulations

This computational suite calculates the bare-hull resistance components for luxury vessels operating across displacement and semi-displacement speed profiles. Total hydrodynamic resistance ($R_t$) is solved by separating viscous fluid friction from wave-making residual configurations:

Total Bare-Hull Resistance
$$R_t = R_f + R_r$$

Where Rf represents viscous skin friction and Rr denotes wave residuary forces.

Viscous Skin Friction ($R_f$)

Frictional scaling is derived directly from the ITTC-1957 correlation line. It maps the dynamic wetted surface area ($S$) against the turbulent fluid Reynolds Number ($Re$):

ITTC-1957 Friction Line
$$R_f = \frac{1}{2} \cdot \rho \cdot V^2 \cdot S \cdot C_f$$

The viscous drag coefficient calculation is driven by: Cf = 0.075 / (log10(Re) - 2)²
