Abstract
This article is dedicated to providing a detailed review concerning the SPH-based hydrodynamic simulations for ocean energy devices (OEDs). Attention is particularly focused on three topics that are tightly related to the concerning field, covering (1) SPH-based numerical fluid tanks, (2) multi-physics SPH techniques towards simulating OEDs, and finally (3) computational efficiency and capacity. In addition, the striking challenges of the SPH method with respect to simulating OEDs are elaborated, and the future prospects of the SPH method for the concerning topics are also provided.
Highlights
Academic Editor: Eugen RusuDuring the past several decades, renewable energy has become the most significant resource for human activities because of the worldwide awareness of the depletion of traditional fossil fuels as well as their harmful impacts on human’s living environment [1].Among various types of renewable energy, ocean energy has been regarded as the preferred one to tackle the dilemma of humans owing to its abundant storage and, more importantly, its very low carbon dioxide emissions [2]
In order to ensure the completeness of the article, we offer a brief recall with respect to the governing equations of the fluid and the fundamental concepts of the Smoothed Particle Hydrodynamics (SPH) method; for a comprehensive description of the methodology, the readers can refer to classical textbooks
This article presented the latest developments of SPH techniques for simulating ocean energy devices (OEDs)
Summary
Academic Editor: Eugen RusuDuring the past several decades, renewable energy has become the most significant resource for human activities because of the worldwide awareness of the depletion of traditional fossil fuels as well as their harmful impacts on human’s living environment [1].Among various types of renewable energy, ocean energy has been regarded as the preferred one to tackle the dilemma of humans owing to its abundant storage and, more importantly, its very low carbon dioxide emissions [2]. As shown, the classification of OEDs can be mainly categorized by their energy resource, i.e., winds (e.g., Floating Wind Turbines, FWTs) [7,8,9,10], waves (e.g., Wave Energy Converters, WECs) [11,12,13], currents (e.g., Tidal Current Turbines, TCTs) [14,15,16], and multi-resource (see e.g., [6]). As pointed out by Said and Ringwood [17], ordinary OEDs consist of four phases to converting ocean energy to electricity (see Figure 2), namely, absorption, transmission, generation, and conditioning. The absorption and transmission phases are typically characterized by Fluid–Structure Interaction (FSI), whereas the generation and conditioning phases mainly involve control strategies.
