Block coefficient of a ship

WebLow prismatic coefficients mean fine ends which can give problems in confining within the ship's lines bulky fittings, like diesel generators, sonar arrays or weapon systems. Optimum block coefficients as a function of F n have been proposed for various types of merchant ships and these are shown in Fig. 15.8. WebHowever, the hydrodynamic force (resistance) coefficient acting on 2D section of the ship hull as the function of ship longitudinal coordinate may be difficult to determine. To overcome this problem, Yoshimura (1988) proposed a simplified cross-flow drag (SCD) model by introducing some hydrodynamic constants.
