![]() To understand the origin and dynamics of planetary magnetic fields, we need to understand the turbulent flow of the huge oceans of rotating, magnetized, low viscosity liquid metal that make up planets’ cores. Planetary Fluid Mechanics in the Lab Dan Zimmerman Nonlinear Dynamics Lab, University of Maryland, College Parkĭownload Presentation (pdf) or view the slides at Finally, I will discuss NREL’s plans to use smooth particle hydrodynamics (SPH) simulation methods to enable high fidelity predictions of wave slamming and overtopping loads from large waves during ocean storms. Specifically, I will discuss our efforts to develop a reduced-order design optimization tool that models WEC devices by coupling time-domain multi-body dynamics simulations with potential flow hydrodynamics models. Next, I will describe NREL's ongoing efforts to develop numerical modeling tools to assist in the wave energy converter design process. In this talk I will first review the current generation of WEC technologies and will describe the challenges that need to be overcome for WECs to achieve commercial viability. Nevertheless, despite decades of research and development, wave energy converters (WECs) are not yet a commercially viable renewable energy generation technology. This finding has renewed commercial and governmental interest in WEC technologies and indicates that wave energy could play a significant role in the US renewable energy portfolio in the years to come. ![]() Recent resource assessment studies indicate that the technically recoverable US wave energy resource is 1400 TW-hr/year, which equals approximately 35% of 2011 US electricity generation.
