Review of state-of-the-art of solar collector corrosion processes. Task 1 of solar collector studies for solar heating and cooling applications. Final technical progress report

Description: The state-of-the-art of solar collector corrosion processes is reviewed, and Task 1 of a current research program on use of aqueous heat transfer fluids for solar heating and cooling is summarized. The review of available published literature has indicated that lack of quantitative information exists relative to collector corrosion at the present time, particularly for the higher temperature applications of solar heating and cooling compared to domestic water heating. Solar collector systems ar… more

Multi-temperature gas chromatography using isothermal columns in series. Technical report

Description: A computer-controlled three-oven gas chromatograph having a multi-position stream-switching valve has been used first to divide a wide-boiling mixture of n-alkanes into three cuts and then to fractionate each cut using a packed column at a different temperature. After initial injection of the sample into the highest temperature column, the low boilers were switched to a low temperature oven. Then, the mid-boilers were switched to a column at an intermediate temperature. For routine repetitive a… more

Heating by the Raman instability

Description: Computer simulations are presented of the reflection and heating due to stimulated Raman backscatter of intense laser light in large regions of underdense plasma. The heated electron distribution is found to be approximately a Maxwellian of temperature (m/sub e//2)v/sub p//sup 2/, where v/sub p/ is the phase velocity of the electron plasma wave. A simple model of the reflection is presented. Raman may cause a pre-heat problem with large laser fusion reactor targets.

Study of corrosion in multimetallic systems. Task 2 of solar collector studies for solar heating and cooling applications. Final technical progress report

Description: Corrosion measurements were made on candidate alloys of construction for non-concentrating solar collectors under simulated conditions of collector operation. Materials evaluated were aluminum alloys 1100, 3003, and 6061, copper alloy 122, Type 444 stainless steel, and 1018 plain carbon steel. The solutions used were equivolume mixtures of ethylene glycol and water, and propylene glycol and water. They were used without corrosion inhibitors but with addition of chloride, sulfate, and bicarbonat… more

Mechanical model for ductility loss

Description: A mechanical model was constructed to probe into the mechanism of ductility loss. Fracture criterion based on critical localized deformation was undertaken. Two microstructure variables were considered in the model. Namely, the strength ratio of grain boundary affected area to the matrix, ..cap omega.., and the linear fraction, x, of grain boundary affected area. A parametrical study was carried out. The study shows that the ductility is very sensitive to those microstructure parameters. The fu… more

Systematic efficiency enhancement in Monte Carlo applications. Final progress report, July 1, 1976-January 31, 1980

Description: Research performed under the grant period has been undertaken as part of the principal investigator's long-term efforts to develop new, more efficient estimators for application to a wide variety of practical problems. Two rather different approaches have characterized the work: (1) the use of a multistage analysis (1) to optimize the efficiencies (variances) of families of estimating random variables in a traditional statistical Monte Carlo framework, and (2) the development of parallel quasi-… more

Methodology for assessing the impacts of alternative rate designs on industrial energy use. Draft report

Description: A task was undertaken to develop a method for analyzing industrial user responses to alternative rate designs. The method described considers the fuel switching and conservation responses of industrial users and the impact to a hypothetical utility regarding revenue stability, annual gas demand, and seasonal fluctuations. Twenty-seven hypothetical industrial plant types have been specified. For each combustor in the plant, the fuel consumption by season, initial fuel type, fuel switching costs,… more
