National Rotor Testbed Rotor Design Integrated Airfoil Performance Results

February 24th, 2015|Categories: Computational Modeling & Simulation, Energy, Facilities, News, News & Events, Renewable Energy, SWIFT, Systems Analysis, Wind Energy|Tags: , , , , , , , , , |

The National Rotor Testbed (NRT) team is examining the effect of airfoil choice on the final design of the new rotor for the Scaled Wind Farm Technology (SWiFT) facility. The airfoil family would ideally be designed to operate in the relevant SWiFT-scale Reynold’s number range, 1–2 million, and be experimentally verified. Two leading options have been identified; one option is the classic utility-scale wind turbine airfoil family, the DU-series. The second option is a combination [...]

Normalized radiative decay rate of a transverse-electric dipole oscillating at the magnetic resonance frequency as a function of the dipole–surface separation for both a 5×5 array approximating our optical magnetic mirror (OMM, red curve) and a gold surface (black curve). The distance of the dipole from the OMM is calculated using the center of the cubic resonator as distance “0,” which is in agreement with our theoretical calculation. First, the oscillatory dependence on distance [...]

“Bionic” Liquids from Lignin: Joint BioEnergy Institute Results Pave the Way for Closed-Loop Biofuel Refineries

December 11th, 2014|Categories: Biofuels, Biomass, Capabilities, Energy, Facilities, JBEI, News, News & Events, Partnership, Renewable Energy, Research & Capabilities, Transportation Energy|Tags: , , , , , , , , |

While ionic liquids (paired-ions salts that are liquid at room temperature) show great promise for liberating fermentable sugars from lignocellulose and improving advanced-biofuel economics, an even more promising candidate is now on the horizon—“bionic” liquids. Bionic liquids derived from lignin and hemicellulose show great promise for liberating fermentable sugars from lignocellulose. The current “standard,” imidazolium-based ionic liquids, effectively and efficiently deconstruct biomass into fuel sugars, but are expensive, and thus limited in industrial [...]

Sandia has implemented a scalable parallel capability to model polarized-fluid dynamics in micro devices driven by an electric potential. The Sandia team discretized the mathematical model (Navier-Stokes and Poisson-Bolzman equations) with an implicit smoothed-particle hydrodynamics (SPH) method. Due to the method’s particle nature, the team used the LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) particle library, which was coupled with Trilinos for linear and nonlinear systems solutions. This was the first time that LAMMPS and Trilinos [...]
