查询词典 hydrodynamic

For the floating body with complex bow and stern, the molded line reconstruction method is adopted to generate the section lines on the bow and on the stern which are necessary to construct the wetted surface, and it can raise efficiency greatly that the intersection lines of intersection structures are obtained by the way of combining modeling tool and NURBS technology; then the patch representation method is adopted in generating the mesh of wetted surface and interior free surface, and the velocity potentials on them are expressed separately, on basis of which the irregular frequency effect is dealt with in the calculation of hydrodynamic coefficients.

Be practical and innovative, our team group work hard to complete the contents of the National Natural Science Foundation Project:"Study of the hydrodynamic behaviors of deep water sea cages". According to the development of the sea cage industry in domestic, two main widely concerning topics were added to our research program. They are the study of Sea station and Quasi-sea station cages. The workload and working strength increased dominately in our research. Delightful results were achieved with 26 science papers been proposed, in which 16 papers have been published or accepted by all kinds of journals or conferences.
