摘要: Abstract This paper examines the side-force and induced drag on two thin bodies in arbitrary separation, stagger, Froude number. The cross-flow by interaction between is addressed placing a doublet sheet body center-plane wake. coupled integral equations for strength are then solved, subjected to boundary conditions Kutta condition at trailing edges. affected camber of surface, yawed angle, thickness neighboring body. It has been shown this that negligible, compared with yaw angle effect. For pair small separation zero experienced each can be thirty percent larger than without certain numbers. However, total two-body system only few variation not sensitive due force cancelation. non-zero staggers, referring their zero-stagger values antisymmetric respect stagger. At high numbers, interact strongly large while lower strong occurs staggers. dominated wave medium
