【 摘 要 】

In this paper, numerical investigation on flow field of flow making system is carried out in the 1:10 scaled model of the multi-purpose basin for the deep sea engineering research center of Dalian University of Technology. According to the requirement of obtaining specified flow velocity in the working area, two kinds of numerical methods simulating pump are used. The calculation results show that the pump simulating method with controlling boundary conditions at inlet and outlet is not valid in the presence of free water surface. The problem is solved by the second pump simulating method in which the pump rotation is simulated in the multiple frame of reference (MRF) system. It is believed that the establishment of current model will provide an effective calculation tool for the simulation of flow characteristics of the deep water flow system.
