Sandia Researchers Win Best Paper Award from the American Institute of Aeronautics and Astronautics

Researchers Joe Oefelein and Guilhem Lacaze (both in Sandia’s Reacting Flow Research Dept.) won the American Institute of Aeronautics and Astronautics’ (AIAA’s) best paper award for their work on scramjet engine simulations. The paper, “A Priori Analysis of Flamelet-Based Modeling for a Dual-Mode Scramjet Combustor,” was a collaboration with Jesse Quinlan and James McDaniel (Univ. [...]

CRF Researchers Are Source for 2015 QTR Sidebar Content

On September 10th, Energy Secretary Ernest Moniz released the second Quadrennial Technology Review (QTR 2015), which examines the most promising research, development, demonstration, and deployment (RDD&D) opportunities across energy technologies to effectively address the nation’s energy needs. Specifically, this analysis identifies the important technology RDD&D opportunities across energy supply and end-use in working toward a [...]

Sandia Optical Diagnostics Researcher Wins DOE Early Career Award

Sandia Combustion Research Facility (CRF) scientist Christopher Kliewer (in Sandia’s Combustion Chemistry Dept.) won a DOE Office of Science (SC) Early Career Research Program award to develop new optical diagnostics to study interfacial combustion interactions that are major sources of pollution and vehicle inefficiency. The funding opportunity for researchers in universities and DOE national laboratories, [...]

Sandia Researchers Are First to Measure Thermoelectric Behavior of a Nanoporous Metal-Organic Framework

Thermoelectric devices convert heat to electricity and have no moving parts, making them extremely attractive for cooling and energy harvesting applications. Thermoelectric metal-organic frameworks (MOFs) could take these advantages a step further with improved performance, smaller size and flexible designs. MOFs have a crystalline structure that resembles molecular scaffolding, consisting of rigid organic molecules linked [...]

Sandia Participates in Office of Science’s National Science Bowl

The Department of Energy Office of Science’s National Science Bowl® (NSB) is a nationwide academic competition that tests middle and high school student teams’ knowledge in all areas of science and mathematics. The DOE created the National Science Bowl® in 1991 to encourage students to excel in mathematics and science and to pursue careers in [...]

CRF Researchers Develop New Approach for Low-Cost Emissions Diagnostics

Monolithic dual-etalon cavity ring-down spectrometer. Modeling and experiments show that it is feasible to perform multiple-species detection at sub-ppm levels with a low-resolution broad-band infrared laser. Target measurement species include CO2, CH, N2O, NO2, SO2, HCl, and CH4, among others, simultaneously, and without process treatment or dehumidification of the exhaust sample—potentially reducing current [...]

Turbulent Mixed-Mode Combustion Studied in a New Piloted Burner

Isometric solid model of the piloted burner (left) and cutaway schematic (right) with dimensions in millimeters. Flame stability is an important trait of practical combustors that impacts combustion emissions and the ability of the combustor to operate effectively with changing fuel and oxidizer compositions and flow rates. Fuel and oxidizer in combustion systems [...]

Direct Measurement of Key Molecule Will Increase Accuracy of Combustion Models

Sandia chemist John Savee (left) identified cycloheptadiene as the best fuel for creating a detectable QOOH, and Sandia computational expert Ewa Papajak (right) and her adviser, Judit Zádor, used quantum chemistry to explain the reaction mechanism. Savee and Papajak appear in front of the Advanced Light Source's Multiplexed Photoionization Mass Spectrometer at Lawrence Berkeley [...]
