FORCE AND MOMENTS ON ASYMMETRIC AND YAWED BODIES IN A FREE SURFACE

Thin bodies with a small degree of asymmetry are assumed to travel with a constant forward speed in the free surface of an infinitely deep ideal fluid. The boundary-value problem for the velocity potential due to asymmetry is derived and its solution formulated in terms of Fredholm integral equations. A numerical scheme based on the finite-element method is developed and applied for two cases of length/draft ratios, namely 7 and 20, at different Froude numbers. Graphs of side force, added-resistance, heeling- and yawing-moment coefficients are presented as functions of Froude numbers. (Modified author abstract)
