3-D TECATE/BREW: Thermal, stress, and birefringent ray-tracing codes for solid-state laser design

Description: This report describes the physics, code formulations, and numerics that are used in the TECATE (totally Eulerian code for anisotropic thermo-elasticity) and BREW (birefringent ray-tracing of electromagnetic waves) codes for laser design. These codes resolve thermal, stress, and birefringent optical effects in 3-D stationary solid-state systems. This suite of three constituent codes is a package referred to as LASRPAK.

101-SY waste sample speed of sound/rheology testing for sonic probe program

Description: One problem faced in the clean-up operation at Hanford is that a number of radioactive waste storage tanks are experiencing a periodic buildup and release of potentially explosive gases. The best known example is Tank 241-SY-101 (commonly referred to as 101-SY) in which hydrogen gas periodically built up within the waste to the point that increased buoyancy caused a roll-over event, in which the gas was suddenly released in potentially explosive concentrations (if an ignition source were presen… more

Advanced direct coal liquefaction concepts. Final report, Volume 2

Description: Integration of innovative steps into new advanced processes have the potential to reduce costs for producing liquid fuels. In this program, objective is to develop a new approach to liquefaction that generates an all distillate product slate at a reduced cost of about US$25/barrel of crude oil equivalent. A Counterflow Reactor was developed in cooperation with GfK mbH, Germany. Advantages are low hydrogen recycle rates and low feed preheating requirements. Coal/heavy oil slurry is injected into… more

Advanced direct coal liquefaction concepts. Quarterly report, January 1, 1994--March 31, 1994

Description: A detailed evaluation of the bench unit data on Black Thunder feedstocks was completed. The results show that in a once-through operation using counterflow, reactor technology coal conversions in excess of 90% could be obtained, giving distillable oil yields in the range 60--65 wt % on MAF coal. The remaining non-distillable oil fraction which represents 20--25 wt % on MAF coal is a source of additional distillable oil in further processing, for example, bottoms recycle operation.

Advanced thermally stable jet fuels. Technical progress report, April 1994--June 1994

Description: Research continued on coal-based, thermally stable, jet fuels. Significant progress has been made on the detection of polycyclic aromatic hydrocarbons present in highly stressed fuels, using high-performance liquid chromatography (HPLC) with diode-array detection. Gas chromatography is not able to detect compounds with {>=}6 fused aromatic rings, but such compounds can be identified using the HPLC method. The concentration of such compounds is low in comparison to aromatics of 1-3 rings, but th… more

Aerovalve Pulse Combustion: Technical Note

Description: The authors present a mathematical model and an experimental investigation of aerodynamically valved pulse combustion. The model uses a control-volume approach to solve conservation laws in several regions of a pulse combustor. Mixing between the fresh charge and combustion products is modeled as a two-step process, with the mixing occurring slowly for a specified eddy time during each cycle, and then changing to a higher rate. Results of model simulations demonstrate that eddy time plays a sig… more
