Sandia Completes Hydrostructural Analysis of Ocean Renewable Power Company’s TidGen® Turbine

Sandia performed an independent hydrostructural analysis of the Ocean Renewable Power Company (ORPC) TidGen® turbine, with a focus on the bolted-joint connections. Sandia’s CACTUS hydrodynamics software was used to predict dynamic loads on the turbine, and these loads served as input to structural dynamics analysis, performed using Abaqus finite-element analysis (FEA) software. The analysis examined [...]

The Influence of Rotor Blade Design on Wake Development

The National Rotor Testbed (NRT) includes research to quantify the degree to which the blade design load distribution influences the rotor near- and mid-wake velocity deficits and fluid structures. Wind-plant performance and the effects of turbine–turbine interaction have been identified as the primary research topics for the NRT blades. The wake deficit and fluid structures [...]

Joint BioEnergy Institute Oxime–NIMS Work Featured on the Cover of ACS Chemical Biology

The oxime-based nanostructure-initiator mass spectrometry (NIMS) work of Kai Deng (in Sandia’s Biotechnology & Bioengineering Dept.) et al. titled “Rapid Kinetic Characterization of Glycosyl Hydrolases Based on Oxime Derivatization and Nanostructure-Initiator Mass Spectrometry (NIMS)” is featured on the cover of ACS Chemical Biology. The multi-institutional team, which also included Jian Shi, Seema Singh, and Kenneth Sale [...]

Understanding Seasonal Effects of WEC Operation using the SNL-SWAN Wave Model Application

Sandia researchers are investigating the seasonal effects of a wave-energy converter (WEC) array on nearshore wave propagation using SNL-SWAN. WECs were simulated as obstacles with frequency-dependent transmission coefficients that were determined based on the incoming wave height and period. The research team created frequency distributions of seasonal wave parameters (significant wave height, peak wave period, [...]

Sandia Student Wins Best Paper Award at IEEE Photovoltaic Specialists Conference

Matthew Reno, a Sandian and an electrical engineering PhD candidate at the Georgia Institute of Technology, was given a Best Student Paper award for research reported in, “Impact of PV Variability and Ramping Events on Distribution Voltage Regulation Equipment” at the 40th Institute of Electrical and Electronics Engineers (IEEE) Photovoltaic Specialists Conference (PVSC) held in [...]
