NUMERICAL, EXPERIMENTAL AND FULL-SCALED INVESTIGATION ON THE CURRENT GENERATION SYSTEM OF THE NEW DEEPWATER OFFSHORE BASIN

摘要

The new deepwater offshore basin was completed in 2008 at Shanghai Jiao Tong University. The current generation system is considered to be one of the most important and challenging equipments in the basin. A lot of work has been conducted to investigate the characteristics of current generation system in the new deepwater offshore basin.Main particulars and equipments of the new basin are described in detail. Some ocean deepwater tests conducted in this new basin are also introduced.Numerical simulation, model test and full-scaled measurements in the real basin were conducted to investigate the hydraulic performances of deepwater current generation system in detail.It can be concluded that the current generation system has satisfactory performances by different methods. Uniform and constant current flows with different current velocities can be generated in this new basin. Several typical current velocity profiles can also be modeled in measuring area of the basin. It indicates that the hydraulic performances of the current generation system can satisfy requirement of offshore model tests in deepwater.
