Study Conversion of Sea Wave Energy to Electrical Energy (Case Study: The Waves of the Caspian Sea)

Ashrafoal Sadat Shekar Baghani    

Abstract: In this study has been evaluated the wave energy resources along the Caspian Sea. The results of the analyses show that the wave energy come, from considerable wave energy resources are in the between South and middle basins of Caspian Sea. The main conclusion coming from the present research would be that the Caspian Sea and especially its Southern part which is shallow water, represents an adequate environment for an effective extraction of the wave energy. In this investigation, Caspian Sea has been considered as stratified and Boussinesq approximation has been considered. In equations governing the movement, cohesion and compressibility have been neglected. In the field studies, investigation of density profiles indicate signs of stratified structure which so far has been attributed to dual distribution convection phenomenon but by considering density ratio profile and values of density ratio which are mostly negative numbers, the factor causing stratified structure of Caspian Sea can be attributed to existence of internal waves. Density field in these two basins indicate that the middle basin has higher average density compared to the South basin this fact can cause creation of a gravity exchange flow. This exchange flow causes creation of internal waves in this sea that can have a modal structure towards vertical direction. In theoretical studies, the two middle and South basins of Caspian Sea are networked in two dimension x-z systems vertical and horizontal velocity profiles obtained from solution of these equations and also density profile obtained indicate that as a result of passage of gravity flow between the two basins, density in various points of the two basins change. So that, by placing the machine in the path of the waves in the Apsheron point is produced electrical energy. Therefore, in transfer and energy conversion, identification of the created strata is of a high importance.
