Abstract: Associated with power production from power plants or fresh water from desalination facilities is the impact on the environment caused by high-temperature discharge or concentrated brine effluents. During the last years, several public-partnership projects have promoted the construction of power plants next to LNG facilities or desalination plants looking for synergy benefits. It becomes necessary to study the impact that the combination of these different types of effluents have in the natural environment. Due to the complexity of these phenomena, the best way to study this interaction is a numerical approach. A commercial CFD package, Flow3D, is used to evaluate the location of the free surface thermal outfall of a new independent power plant to be constructed in Korea. Besides, the influence received by the thermal plume due to the submerged intake risers of an adjacent LNG is evaluated in this study. This near field simulation will give a first description of the temperature dispersion around the near-shore of this industrial development. Besides, the result from the near field simulations will be compared with a preliminary recirculation study performed by using MIKE21 and MIKE3 developed by the Danish Hydraulic Institute (DHI). From the comparison of both flow fields the importance of adding near field simulation results into higher scale recirculation studies was observed.
