Calculations are presented of the rate of energy conversion of the barotropic tide into internal gravity waves above topography on the ocean floor. The ocean is treated as infinitely deep, and the topography consists of periodic obstructions; a Green function method is used to construct the scattered wavefield. The calculations extend the previous results of Balmforth et al. for subcritical top...

Ocean wave height is one of the critical factors to decide efficiency ocean energy conversion system. Usually, only when resonate occurs between (ocean speed in vertical direction) and system, can from into electric be maximized. Therefore, this paper proposes two predication methods predict future 1.5–2.5 s. Firstly, data fitting real achieved by polynomial method, which beneficial height. Sec...

Ocean Thermal Energy Conversion (OTEC) is a promising renewable energy technology that the most economical at large scale. But contemporary literature does not address how OTEC could reach such scale with current technology, and what techno-economic impact of location-dependent factors technological learning are. This paper tackles these issues by simulating OTEC's upscaling model implements to...

Ocean Thermal Energy Conversion (OTEC) produces electricity using the temperature difference between warm surface and cold deep-sea water. OTEC systems in literature only limitedly consider seasonal seawater variations thus might not be adequately sized for off-design conditions. This potentially leads to techno-economically sub-optimal design choices. paper sheds light on which approach yields...

Ocean thermal energy conversion (OTEC) is a solution for environmental and climate change issues in the tropics. The OTEC potential Malaysia using ocean conditions bathymetry data has been previously studied demonstrated. Following this, it vital to perform basic performance analysis of 10 MW Rankine Cycle plant Malaysian conditions. In this paper, results heat mass balance will be reported cyc...

This article reports the off-design performance analysis of a closed-cycle ocean thermal energy conversion (OTEC) system when a solar thermal collector is integrated as an add-on preheater or superheater. Design-point analysis of a simple OTEC system was numerically conducted to generate a gross power of 100 kW, representing a base OTEC system. In order to improve the power output of the OTEC s...
