Set Up

The Oscillating Water Column (OWC) is one of the simplest and most studied concepts for wave energy conversion. The commercial scale diffusion of the OWC technology is, however, strongly dependent upon the device optimization. Research at a fundamental level is therefore still required. Analytical, numerical and experimental models are necessary tools for advancing in the knowledge of the system and thus promoting its passage at the commercial level. In this work, a simplified frequency domain rigid piston model has been applied to preliminary select expected ranges of air pressures and air velocities for the instrumental set up of laboratory experiments. The set up of a Computational Fluid Dynamic (CFD) model implemented in the open source OpenFOAM®1 environment is then presented. The multiphase model solves incompressible 3D Navier-Stokes equations, using Large Eddy Simulation (LES) for turbulence modelling, and adopts a Volume of Fluid method (VOF) to track the air-water interface. A preliminary validation of the model with physical tests data is conducted. The numerical approach seems to be promising for an accurate simulation of the OWC device energy conversion process. Hence, the validated model can be a useful research tool for different problems, particularly for systematic parameter studies to extend the range of conditions tested in the laboratory.

Central Sulawesi

Growth electricity consumption in central sulawesi encourages increased utilization of conventional resources such as petroleum products and coal as alternative energy plant. It causes some adverse effect either on the environment, health and economy. As a result, the alternative of conversion energy from non-conventional resources must be provided. Central Sulawesi with coastline about 4,013km has immense potential in developing wave energy as an alternative of Renewable Energy Resource. This paper investigated the potential for wave energy conversion in Lindau Water as an alternative of power plant by using Oscillating Water Column System (OWC). The value of significant wave height and periods are calculated based on the Wilson method, which is then analysed to determine the potential of electricity that feasible converted from wave energy in Lindau waters and potential to applicated wave energy conversion using OWC in Lindau Waters. The result found the conversion of Lindau waters wave energy produce the largest power that can be converted is about 21. 000 watts. Its shows the potential that can be applied to coverage the need electricity by using wave energy in Alindau Village.
