Retrieving Temperature and Moisture Profiles from AERI Radiance Observations: AERIPROF Value-Added Product Technical Description Revision 1

Description: This document explains the procedure to retrieve temperature and moisture profiles from high-spectral resolution infrared radiance data measured by the U.S. Department Of Energy (DOE) Atmospheric Radiation (ARM) Program’s atmospheric emitted radiance interferometer (AERI) instrument. The technique has been named the AERIPROF thermodynamic retrieval algorithm. The software has been developed over the last decade at the University of Wisconsin-Madison and has matured into an ARM Value-Added Proce… more

Thermionic Technology Program: A, Insulator test and evaluation: Final report

Description: The Thermionic Technology Program (TTP) consisted of two major efforts, evaluation of insulators and evaluation of thermionic converters. This report details the work performed on the insulator phase of the program. Efforts were made to better understand the mechanisms involved in the electrochemistry of insulators at elevated temperatures by modelling the ionic transport through the various layers of the insulator package. Although rigorous analytic solutions could not be obtained owing to a l… more

User's manual for steady-state computer simulation for air-to-air heat pumps with selected examples

Description: A steady-state computer simulation model has been developed for conventional, vapor compression cycle, electrically driven air-to-air heat pumps. Comparison between the heat pump simulation model predictions and available data from three heat pump experiments indicate that the predictions generally are within accepted tolerances. A sensitivity analysis was made to assess the effect of possible variations in some of the input parameters on the system's thermal performance. The computer simulatio… more

Similarity solutions for convection of groundwater adjacent to horizontal impermeable surfaces with axisymmetric temperature distribution. Technical report No. 14

Description: The axisymmetric buoyancy-induced groundwater flow adjacent to horizontal impermeable surfaces with wall temperature being a power function of radius is discussed in this paper. With the boundary layer simplifications, the governing non-linear partial differential equations can be transformed into a coupled pair of non-linear ordinary differential equations with two-point boundary conditions that can be integrated numerically by established techniques. Simple algebraic expressions for boundary … more

DEVELOPMENT OF A VALIDATED MODEL FOR USE IN MINIMIZING NOx EMISSIONS AND MAXIMIZING CARBON UTILIZATION WHEN CO-FIRING BIOMASS WITH COAL

Description: This is the sixth Quarterly Technical Report for DOE Cooperative Agreement No. DE-FC26-00NT40895. A statement of the project objectives is included in the Introduction of this report. Two additional biomass co-firing test burns were conducted during this quarter. In the first test (Test 10), up to 20% by weight dry hardwood sawdust and switchgrass was compiled with Galatia coal and injected through the dual-register burner. Galatia coal is a medium-sulfur Illinois Basin coal ({approx}1.0% S). T… more

Automatic ID heat load generation in ANSYS code

Description: Detailed power density profiles are critical in the execution of a thermal analysis using a finite element (FE) code such as ANSYS. Unfortunately, as yet there is no easy way to directly input the precise power profiles into ANSYS. A straight-forward way to do this is to hand-calculate the power of each node or element and then type the data into the code. Every time a change is made to the FE model, the data must be recalculated and reentered. One way to solve this problem is to generate a set… more

Feasibility of using saturated solar ponds for brine unmixing. Final report

Description: The overall objective of this study was to investigate in the laboratory the feasibility of using saturated solar ponds for unmixing a brine of intermediate concentration into dilute and concentrated brine streams for salinity gradient energy conversion systems. This objective was accomplished by conducting experiments on laboratory saturated ponds using borax, potassium perchlorate, potassium nitrate, disodium phosphate and potassium alum. Results from ponds using borax, potassium nitrate and … more

Effect of Insolation Boundary Conditions on Type B Package Internal Temperatures

Description: The prescription of the initial conditions and the final conditions for a thermal accident for Type B packages are different for differing regulations. This paper presents an analytical method for estimating the effect of the boundary conditions on post-fire peak internal package temperatures. Results are given for several boundary conditions for a Type B drum-type package.

Combustion Turbine (CT) Hot Section Coating Life Management

Description: The integrity of coatings used in hot section components of combustion turbines is crucial to the reliability of the buckets. This project was initiated in recognition of the need for predicting the life of coatings analytically, and non-destructively; correspondingly, three principal tasks were established. Task 1, with the objective of analytically developing stress, strain and temperature distributions in the bucket and thereby predicting thermal fatigue (TMF) damage for various operating co… more

Spent fuel test - Climax: technical measurements. Interim report, fiscal year 1981

Description: The Spent Fuel Test-Climax (SFT-C) is located 420 m below surface in the Climax granite stock on the Nevada Test Site. Eleven canisters of spent nuclear reactor fuel were emplaced, and six electrical simulators were energized from April to May 1980, initiating the 3- to 5-year-duration test. The SFT-C operational objective of demonstrating the feasibility of packaging, transporting, storing, and retrieving highly radioactive fuel assemblies in a safe and reliable manner has been met. Technical … more

Description: This is the second Quarterly Technical Report for DOE Cooperative Agreement No. DE-FC26-00NT40895. A statement of the project objectives is included in the Introduction of this report. Two biomass co-firing test burns have been conducted. In the first test, up to 20% by weight dry hardwood sawdust and dry switchgrass was co-milled Pratt seam coal. In the second test, also with Pratt seam coal, up to 10% by weight dry hardwood sawdust was injected through the center of the burner. Progress has c… more

Quench Protection of High Field Nb{sub 3}Sn Magnets for VLHC

Description: Fermilab is developing high field magnets for a possible future VLHC. The high levels of stored energy in these magnets present significant challenges to the magnet quench protection. Simulation programs have been developed and used to analyze temperature and voltage distributions during a quench and to performed parametric studies on conductor and quench-heater requirements. This paper concludes with a proposal for a set of quench protection parameters for the VLHC magnets.
