摘要

本研究探讨了由于社会经济发展带来的需求增长,全球向可再生能源的转变。由于化石能源的有限性,人们对海洋可再生能源的兴趣与日俱增,据估计,海洋可再生能源约为 7600 万兆瓦。亚马逊河流域潜力巨大,尤其是河口可预测的潮汐流。阿马帕内大陆架受排水量(5.7×1012 立方米/年-1)、信风(风速:5-10 米/秒-1)以及中潮和大潮等因素的影响,是一个值得注意的地区。本文侧重于考虑不同潮汐情况的流体力学模拟,旨在评估潮汐流的能量潜力。研究使用 SisBaHiA 二维水动力模型,评估了关键区域的功率密度。春-夏周期模拟确定了瓦拉多水道上段(潮汐流速为 1,53 m.s- 1- 1.835 W.m-2)和下段(潮汐流速为 1,12 m.s- 1- 720,03 W.m-2)的有利区域。值得注意的是,靠近 "地狱 "岛(马拉卡岛)的瓦拉多尔海峡上段显示出更大的能量密度,突出了其在春季和秋季周期的潜力。这项研究有助于深入了解阿马帕地区潮汐流的可再生能源潜力,支持可持续能源开发。

Assessment of tidal current potential in the Amapá’s inner continental shelf (Eastern Amazonia - Brazil)

Assessment of tidal current potential in the Amapá’s inner continental shelf (Eastern Amazonia - Brazil)

This study addresses the global shift towards renewable energy due to the increasing demand driven by socioeconomic development. With finite fossil energy sources, there’s a growing interest in oceanic renewable energy, estimated at 76 million MW. The Amazon, with its significant potential, particularly from predictable tidal currents in estuaries, stands out. The Inner Continental Shelf of Amapá, influenced by factors like water discharge (5,7 × 1012 m3.year− 1) and trade winds (speed: 5–10 m.s− 1) as well as Meso and Macrotidal, is a notable region. The paper focuses on hydrodynamic simulations considering different tidal scenarios and aims to assess the energy potential of tidal currents. Using the SisBaHiA two-dimensional hydrodynamic model, the study evaluates power density in key areas. The spring-neap cycle simulations identify promising zones in the Varador channel—upper section (tidal current velocity of 1,53 m.s− 1– 1.835 W.m− 2) and lower section (tidal current velocity of 1,12 m.s− 1 – 720,03 W.m-2). Notably, the upper Varador channel near the Inferno ¨igarapé¨ (Maraca Island) exhibits greater energy density, highlighting its potential in both spring and neap cycles. This research contributes valuable insights into the renewable energy potential of tidal currents in the Amapá region, supporting sustainable energy development.
