New Conceptual Insights into Diesel Engine Fuel-Injection Processes

By combining advanced theory and high-fidelity large eddy simulation, Combustion Research Facility (CRF) researchers Rainer Dahms and Joe Oefelein (both in 8351) have provided new conceptual insights that promise to improve the understanding and prediction of fuel-injection processes in high-pressure diesel engine conditions. Their results, which experiments performed by CRF researchers Lyle Pickett and Julien [...]

Second Annual Electric Power Research Institute/Sandia Photovoltaic Systems Symposium

Sandia and Electric Power Research Institute (EPRI) are delighted to host the second joint symposium on technical issues related to photovoltaic (PV) systems and related technologies. This year, the symposium will cover three areas: PV performance modeling; screening methods, distribution PV host­ing capacity, and advanced inverter modeling; and PV system reliability and maintenance strategies. Sandians [...]

National Rotor Testbed Functional Scaling Presented at American Institute of Aeronautics and Astronautics 2014 Scitech

David Maniaci (in Sandia’s Wind Energy Technologies Dept.) traveled to National Harbor, Maryland, in January to present a paper at the American Institute of Aeronautics and Astronautics (AIAA) SciTech/American Society of Mechanical Engineers Wind Energy Symposium titled, “Definition of the National Rotor Testbed: An Aeroelastically Relevant Research-Scale Wind Turbine Rotor.” Approximately 60 researchers from various institutions [...]

Scaled Wind Farm Technology Facility Baselining Project Accelerates Work

With the Scaled Wind Farm Technology (SWiFT) facility’s basic operation and data collection now operational, the SWiFT Baselining Team met at Sandia on February 20th to kick-off the SWiFT Facility Baselining Project’s major work phase. The project’s goal is to achieve complete operational readiness and verification of all SWiFT controller, data acquisition, and instrumentation systems for future [...]

Increasing the Scaled Wind Farm Technology Facility’s Power Production

During the period of February 24–March 7, Scaled Wind Farm Technology (SWiFT) facility turbines were operational—producing power and collecting data for the longest period to date. On March 5, both turbines produced rated power of 200 kW without any issue. A snapshot of 184 kW is shown in the figure. To date, the turbines have been running with supervised operation [...]
