Algorithm for energy-derived potential flow hydrodynamic coefficients
An algorithm is described to compute steady and unsteady hydrodynamic coefficients from added mass tensors without the need to develop highly intense and system dependent algebraic expressions and computer codes, especially when complex motions are admitted. Lagrange's equation is applied in fi...

| description | An algorithm is described to compute steady and unsteady hydrodynamic coefficients from added mass tensors without the need to develop highly intense and system dependent algebraic expressions and computer codes, especially when complex motions are admitted. Lagrange's equation is applied in fixed coordinates. Coordinate transformations are accomplished to obtain an efficient algorithm for six-degrees-of-freedom coefficients for bodies hydrodynamically defined with time varying added mass tensors. In addition to infinite fluid, the algorithm is applicable to restricted classes of emerging body and free surface conditions. (Author) |
