Sustainable energy is needed globally, and Ocean Thermal Energy Conversion (OTEC) a possible way to diversify the matrix. This article suggests preliminary selection process find optimal sites for OTEC deployment on Mexican coastline. The method comprises (1) evaluation of thermal power potential, using daily data (16 years) sea surface temperature, percentage available time thresholds; (2) ass...

This study selects five parameters as decision variables for the optimization design of an ocean thermal energy conversion system, including evaporating temperature, condensing pinch-point temperature difference between evaporator and condenser, working fluid flow rate. The goal is to maximize net output power per unit area exergy efficiency. final scheme comprehensively screened out from Paret...

This study investigated the seasonality of tropical instability waves (TIWs) and its feedback to the seasonal cycle in the tropical eastern Pacific using a high-resolution ocean model covering 1958-2007. The climatological mean of the TIWs featured intraseasonal fluctuations, implying that TIWs are not occurring randomly, but their amplitude is partly in phase from one year to another. This sea...

Nowadays, policies are being developed in many countries in order to decrease their greenhouse gases emissions. While in this area some technologies are widely installed (wind and solar energy), other ones, like the sea energy, could get an important role in the medium and long term. That is why the most relevant technologies associated to the sea energy conversion are presented in this paper: ...

Using linear wave theory, the rate at which energy is converted into internal gravity waves by the interaction of the barotropic tide with topography in an ocean is calculated. Bell’s formula for the conversion rate is extended to the case of an ocean of finite depth H with weak two-dimensional topography h(x, y) and arbitrary buoyancy frequency N(z). Approximate solutions are computed using th...

Recently, various forms of ocean energy such as wave, tidal, marine current, and ocean thermal energy conversion are considered as source of alternative clean energy because of the increased oil price, international political issues, and global warming issues, etc. For this reason, underwater robot is believed to play a key role in both development and protection of the ocean. Until now, underw...
