Virtual simulation technology has become one of the core technologies in deep ocean research and exploration. In order to guarantee the reliability of underwater operating simulation, it is of vital importance to consider the physical influence on machinery equipments from complex ocean currents. In this paper, a dynamics computational model of Ekman flow with physical characteristics of the ocean operation area is designed to support real-time ocean simulation. And based on hydrodynamics algorithms and physical modeling techniques of Vortex, a software module for ocean dynamics simulation is developed. The simulation results indicate that the module can meet the requirements for both high dynamics accuracy and real-time performance.
