Thermal depletion of a geothermal reservoir with both fracture and pore permeability

Description: A method for estimating the useful lifetime of a reservoir in porous rock where the injection and production wells intersect a fracture system is presented. Equations were derived for the pore-fluid and fracture-fluid temperatures averaged over large regions of the geothermal field. Problems such as incomplete areal sweep and interfingering of cool and hot fluids are ignored. Approximate equations relating average temperatures to the heat flowing from rock to fluid were developed, and their use… more

Feedback as a means of decreasing residential energy consumption. Report PU/CES 34

Description: When residential units are analyzed in human factor terms, it is apparent that the consumption level feedback (typically a bill, calculated once a month, over all appliances) is inadequate to give the resident useful information about his energy consuming actions. The present study tested the hypothesis that providing immediate feedback to homeowners concerning their daily rate of electric usage would be effective in reducing electric consumption. In the studied homes, central air-conditioning … more

Correlation of AES FY 1978 program with energy-related environmental research needs

Description: This report has a two-fold objective: (1) to identify major energy-related environmental concerns, needs, and problem areas, and (2) to show the relationship of the planned FY 1978 research program of the ERDA Assistant Administrator of Environment and Safety (AES) to those environmental issues. The document is organized into sections addressing each major energy form. Each section identifies environmental issues of an energy form and indicates the level of planned FY 78 AES research addressing… more

Burrs produced by grinding

Description: An investigation was conducted to determine the influence of variables in controlling the size and repeatability of grinding burrs to minimize burr-removal costs and improve the quality and reliability of parts for small precision mechanisms. Each of the three types of burrs produced by surface-grinding a rectangular block responds differently to changes in cutting conditions. Reducing the downfeed rate generally produces shorter burrs. Although the size of the abrasive grain affected the thick… more

Creep of circular plates using a state-variable approach

Description: The technical theory of bending of circular plates under axisymmetric lateral loads is formulated in terms of Hart's state-variable equations. Then the method is applied to plates with simply supported and clamped edges through a standard algorithm. All the analytical results obtained compare qualitatively with those reported in the literature. The influence of the state variable called ''hardness'' is clearly demonstrated. Thus the analysis and the results provide a basis for acceptance of the… more

End stoppering in mirror machines

Description: Like toroidal confinement, confinement by a potential barrier offers the possibility of unlimited Q if the barrier is good enough. For a barrier height PHI, approximately tau approximately equal to tau/sub collision/ exp PHI/T/sub i/. These notes review previous ideas about how to establish a potential barrier at the ends of a mirror machine and we also discuss a different possibility using mirror confinement itself to establish a barrier utilizing the positive ambipolar potential characteristi… more
