Popis:	The vorticity transport integral (VTI) concept affords an anaIytica1 procedure that is well suited to determining the wave lnrces on bodies and structural dements in a marine environment. The concept can be applied to any unsteady flow; however, it is especially suited lo the treatment of flows assucimted with ocean waves in which an object experiences complete flow reversal with wake motion confined to the vicinity of the body. As ad integral approach it allows forces to be determined accurately with either an approximate description ar an exact soluliun uf the flow. Because the integrals have significadt values only near the body, the approach avoids the problems inherent with the evaluation of integrals over large volumes of fluid. The resulting expresslonu are used in a qualitative appraise1 of the varlous contributions to the tots1 force on a body in an unsteady flowfleld.
