Optimal Ship Forms for Minimum Wave Resistance,

Abstract

By introducing a set of 'tent' functions to approximate the ship hull function, the Michell integral for wave resistance is reduced to a standard quadratic form in terms of ship offsets. With linear-inequality constraints of the type 0 less than or equal to H(x,z) less than or equal to B; C less than or equal to Hx(x,z) less than or equal to D, (H(x,z) is hull function; B, C, D are constants), it is possible to find various optimal ship forms of minimum wave resistance by applying quadratic programming techniques to the problem. Three optimal forms have been chosen among a number of computed results for tests in the ship-model towing tank. (Author)
