Outdoor sources of indoor air pollution

Description: Conservation measures that seal a building, like storm window installation, can significantly reduce its energy requirements. These measures also protect its occupants from air pollutants having outdoor sources but amplify any harmful effects of those generated indoors. Using these Fourier series techniques and an approximation of outdoor pollution peaks by step functions, we obtained the following results: the average daily concentration indoors is the same as outdoors for any pollutant with n… more

Initial results from the first Los Alamos hot dry rock energy system

Description: The pressurized-water loop for extraction of natural heat from dry crustal rock is, as this is written, eight weeks into its initial long-term continuous circulation test. During most of this time, flow-impedance through the man-made fracture system has decreased continuously so that, with a nearly constant pressure difference between injection and recovery wells, flow rate has increased steadily to the maximum capacity of the surface piping--about 16 liters per second. Temperature of water ent… more

Numerical study of boundary layer injection as a scale control method

Description: A boundary layer injection method of controlling scale-buildup in geothermal two-phase flow nozzles is studied. The object of this study is to set an upper limit on the ratio of the injected mass flow rate to the free stream mass flow rate that is necessary to isolate the scale carrying free stream flow from the nozzle wall. In order to develop a numerical model of the boundary layer flow, assumptions are made which reduce the results to order of magnitude approximations. Two configurations of … more

Water testing of the inducer pump. [LMFBR]

Description: The inducer pump, designed and fabricated as a test article to evaluate the inducer/impeller pump concept for providing improved suction performance of large sodium pumps, met or exceeded all performance goals. The inducer stage in front of the centrifugal impeller dramatically reduces the size of pumps. It was demonstrated that the inducer can operate at suction specific speeds in excess of 35,000, whereas conventional centrifugal pumps have demonstrated capability to only 12,000. The inducer … more

Description: The revised ambient-temperature NaK-nitrogen facility is described. The maximum liquid flow rate and generator inlet pressure are 10.9 kg/s 200 gpm) and 1.48 MP/sub a/ absolute (200 psig), respectively, compared with the previous values of 6 kg/s (110 gpm) and 0.72 MPa absolute (90 psig). Satisfactory loop operation has been obtained, and new experiments with the second diverging-channel generator were completed. The principal experimental results were a higher power density for the same genera… more

Turbulent diffusion of small particles

Description: The diffusion of small, spherical, rigid particles suspended in an incompressible turbulent fluid, but not interacting with each other, was studied. As a stochastic process, the turbulent fluid velocity field is assumed to be homogeneous, isotropic and stationary. Assuming the Stokes regime, a particle of equation of motion is used which includes only the effects of Stokes drag and a virtual mass force and an exact solution is found for the particle velocity correlation function, for all times … more

Geothermal reservoir assessment: Cove Fort-Sulphurdale Unit. Final report, September 1977-July 1979

Description: Three exploratory geothermal wells were drilled in the Cove Fort-Sulphurdale geothermal resource area in southwestern Utah to obtain new subsurface data for inclusion in the US DOE's geothermal reservoir assessment program. Existing data from prior investigations which included the drilling of an earlier exploratory well at the Cove Fort-Sulphurdale area was also provided. Two of the wells were abandoned before reaching target depth because of severe lost circulation and hole sloughing problems… more

Field electrochemical measurements of corrosion characteristics of materials in hypersaline geothermal brine

Description: A flow cell (with appropriate accessories) was developed for use in short-term testing of the corrosion behavior of materials in approximately 100{sup 0}C, hypersaline geothermal brine. The apparatus was designed to accommodate commercial (Petrolite) corrosion measurement equipment and conducted experiments on-line at the Lawrence Livermore Laboratory Test Station in the Salton Sea Geothermal Field. The apparatus also permitted direct readings of corrosion potentials, solution redox potential (… more

Investigation of methods to transfer heat from solar liquid-heating collectors to heat storage tanks. Final report

Description: A study was made of the methods available to transfer heat from the collector to the water storage tank in water heating systems. In counterflow heat exchangers used in double loop water heating systems, it was found to be more important to use a high water flowrate than a high heat transfer fluid flowrate. It was earlier thought to be best to have matched WC/sub p/ (mass flowrate-specific heat) products in the loops. It was shown in this study that the water WC/sub p/ product should be about t… more

Problems associated with transuranium determination of suspended solids in seawater samples

Description: Particulate material collected by filtration from the north Equatorial Pacific Ocean has been analyzed for plutonium and other radionuclides. Different filter pore size, types of filter substrates, flow rates, and sample volumes were evaluated. Retention of /sup 239 +240/Pu was found to vary with the sample volume filtered and was not greatly affected by the type of filter substrate, flow rate, or porosity tested. About 7 +- 3% of the /sup 239 +240/Pu activity in north Equatorial Pacific surfac… more

Heat transfer to isobutane flowing inside a horizontal tube at supercritical pressure

Description: An experimental measurements of heat transfer coefficient of isobutane at 4.14 MPa (600 psia) has been performed using the experimental system developed by the Sea Water Conversion Laboratory. The experimental system simulates a geothermal power plant utilizing a binary cycle with isobutane as the working fluid.

Posttest RELAP4 analysis of LOFT experiment L1-4

Description: Results of posttest analysis of LOFT loss-of-coolant experiment L1-4 with the RELAP4 code are presented. The results are compared with the pretest prediction and the test data. Differences between the RELAP4 model used for this analysis and that used for the pretest prediction are in the areas of initial conditions, nodalization, emergency core cooling system, broken loop hot leg, and steam generator secondary. In general, these changes made only minor improvement in the comparison of the analy… more

Application of wind energy to Great Plains irrigation pumping. Final report

Description: Wind energy systems without energy storage for irrigation in the Great Plains are studied. Major uses of irrigation energy were identified as pumping for surface distribution systems, which could be supplied by variable flow, and pumping for sprinkler systems using constant flow. A computer program was developed to simulate operation of wind-powered irrigation wells. Pumping by wind turbine systems was simulated for 2 variable and 2 constant flow operational modes in which auxiliary motors were… more
