AbstractOcean is usually consisted of complicated waves and currents motions. Thus waves and currents are always very important topics in fluid hydrodynamics. Waves and currents and their consequent interactions play a very important role in most of the ocean dynamic processes. So it is crucial to understand the effects of waves on currents and vice versa in the laboratory to design any ocean structure. Equipment that can generate vertically distributed uniform current would be an important tool for relevant model testing in the Offshore Engineering Basin (OEB) of IOT. The aim of this project is to study different physical characteristics of a current generator, such as its height, nozzle length, diameters of different sections, inlet size, single and multiple impeller-type and impeller characteristics that would provide best possible performance of the current flow. This final equipment would be a portable one and can be placed at any location and directions in the OEB. Flow-3D CFD code is used to simulate those characteristics. Results are shown in a systematic ways. An example is also given that shows how a current can reduce the height of an incoming wave field.
