dc.description.abstract | A series of numerical simulations were carried out to investigate the current generation performance in deepwater ocean engineering basin (DOEB) of KRISO. In the numerical simulations, unsteady Reynolds averaged Navier-Stokes (RANS) equations were solved to study the flow characteristics of the current generated in the basin. Three different current profiles, i.e. uniform, Gulf of Mexico (GoM) and Brazil profiles, were directly generated by applying the same current generation system as the DOEB and their accuracy was examined. In addition, an optimization algorithm based on cost function is newly proposed to control the inlet and outlet velocities of the multiple culverts for the desired current velocity profile. Through various numerical simulations, discussion are made on free surface elevation, effect of initial ramping operation, effect of false bottom plate, and full 3D simulation.
