Light duty vehicle fuel consumption model, 1975-1986 (open access)

Light duty vehicle fuel consumption model, 1975-1986

The report summarizes the Light Duty Vehicle Fuel Consumption Model developed for the Office of Conservation and Advanced Energy Systems Policy in the Department of Energy. The purpose of the model is to estimate annual passenger auto (PA) and non-passenger auto (NPA) fuel consumption through 1986. The model is intended to: (1) provide information on future estimated petroleum demand for the majority of the US transportation sector; and (2) generate a better understanding of the trends in fuel consumption in light of fuel economy standards issued by the Department of Transportation (DOT) under the Energy Policy and Conservation Act of 1975 (EPCA). The model also is designed to provide disaggregated data for PA's and NPA's in order to anayze their relative importance in estimating total fuel consumption and to calculate the proportion of diesel, leaded, and unleaded fuels in total fleet consumption.

Conceptual studies and preliminary design of a fluid bed fired boiler for service in an electric utility (open access)

Conceptual studies and preliminary design of a fluid bed fired boiler for service in an electric utility

As a part of this study, B and W was to develop fluid bed system design bases and parameters using any and all sources available. The design parameters used for the fluid bed boiler designs in this study were actually developed by B and W as part of their in-house AFB development program and also as a part of the subject design study. To properly carry out the assessment portion of the work it was essential to develop an understanding of the basic interrelationship of variables in order that the final comparisons would be of consistent and realistic as possible. Inputs to meet this goal were largely based on available literature, B and W experience, and engineering judgment. In some cases we also had to venture into some theoretical development work if published results appeared incomplete. The key subject areas to be covered in subsequent pages are listed: General, Fluidizing Velocity Requirements, FBC Feed Particle Size Requirements, Calculated Slip Velocities as a Function of Particle Size and Dispersed Density, Heat Transfer Equations, Heat Transfer to Horizontal Tubes in Shallow Fluidized Beds, Combustion Efficiencies, Sulfur Capture, Freeboard Performance, Distributor Plate Design, and Economic Considerations.

Acoustic emission intrusion detector (open access)

Acoustic emission intrusion detector

In order to improve the security of handling special nuclear materials at the Oak Ridge Y-12 Plant, a sensitive acoustic emission detector has been developed that will detect forcible entry through block or tile walls, concrete floors, or concrete/steel vault walls. A small, low-powered processor was designed to convert the output from a sensitive, crystal-type acoustic transducer to an alarm relay signal for use with a supervised alarm loop. The unit may be used to detect forcible entry through concrete, steel, block, tile, and/or glass.
