摘要

由于受化石燃料的影响,能源危机和全球变暖的挑战反复出现,向地热能等可再生能源的转变已成为必然趋势。使用形状记忆合金(SMA)热机进行地热-机械能转换是利用地热能的一种新颖、可持续的方法。形状记忆合金因能够在温度变化的驱动下发生可逆相变而闻名,是热能-机械能转换的理想材料。本文探讨了利用地热热源驱动机械功的 SMA 热引擎的设计和性能。该发动机在高温地热环境和较冷的水槽之间循环运行,利用形状记忆效应产生机械运动。通过整合地热能源和 SMA 技术,该系统为可再生能源发电提供了一个潜在的解决方案,可应用于偏远或离网地区。论文还研究了输出功率和热力学效率。本文建立了一个模型,并模拟了发动机的行为。对发动机的输出功率和效率进行了一系列实验。将模型与实验数据进行比较,以进行验证。发动机在 60、80 和 90 °C 时的最大功率分别为 3.5、8.5 和 11.5 瓦。所提出的基于 SMA 的地热-机械能转换系统为高效、可靠和可扩展的地热能采集提供了一种前景广阔的解决方案。这项研究有助于开发创新、高效的地热能转换技术,支持全球可再生能源目标,减少温室气体排放。这种创新的能源转换机制可在未来的可持续发电领域发挥关键作用。

Geothermo-mechanical energy conversion using shape memory alloy heat engine

The shift towards renewable energy sources like geothermal energy has become desirable due to the recurrent energy crisis and global warming challenges influenced by fossil fuels. Geothermo-mechanical energy conversion using shape memory alloy (SMA) heat engines presents a novel and sustainable approach for harnessing geothermal energy. Shape memory alloys, known for their ability to undergo reversible phase transformations driven by temperature changes, are ideal for thermal-to-mechanical energy conversion. This paper explores the design and performance of an SMA heat engine that utilizes geothermal heat sources to drive mechanical work. The engine operates by cycling between the high-temperature geothermal environment and a cooler sink, exploiting the shape memory effect to generate mechanical motion. By integrating geothermal energy and SMA technology, this system offers a potential solution for renewable energy generation, with applications in remote or off-grid locations. The paper also investigates output power and the thermodynamic efficiency. A model is formulated and the engine behavior is simulated. A series of experiments are conducted for engine output power and efficiency. The model is compared to the experimental data for validation. The engine developed a maximum power of 3.5, 8.5, and 11.5 watts at 60, 80, and 90 °C respectively. The proposed SMA-based geothermo-mechanical energy conversion system offers a promising solution for efficient, reliable, and scalable geothermal energy harvesting. This research contributes to the development of innovative, efficient geothermal energy conversion technologies, supporting global renewable energy goals and reducing greenhouse gas emissions. This innovative energy conversion mechanism could play a key role in the future of sustainable power generation.
