The study of boiler saline concentrations and a determination of a more efficient boiler blowdown procedure
The importance of the feedwater problem and the meager knowledge of existing feedwater conditions make it desirable to conduct a study of boiler salines at the V.P.I. power plant. A determination of the critical concentrations of the boiler salines at various loads was to be made and an optimum …

Manometric determination of the biochemical oxygen demand of sulfite paper mill wastes
… studied. The wastes studied included raw sewage, blowdown liquor and total mill wastes from a semichemical pulp mill, and effluent from an anaerobic, sewage-blowdown liquor digester. The concentrations of microorganisms used ranged from 3.4 to 17.0 milligrams of dry bacterial cells in a total …

Experimental assessment of the internal flow behavior of supercritical carbon dioxide
… CO₂ into the two-phase region. An experimental blowdown test-rig with a modular test section was developed with the capability of operating a converging-diverging nozzle with a wide range of charge conditions. The test-rig demonstrated repeatable results with relative errors of less than 1 …

Predicting invadedness of forested protected areas in relation to natural and anthropogenic disturbances
… areas of undisturbed forest. I expected forest blowdown areas to be more heavily invaded than undisturbed forest since a decrease in tree canopy provides increased resources, such as light, to invasive plants. I then sought to determine the effects of time since disturbance and disturbance …

An economic study of the present feedwater treatment system at the V.P.I. power plant
… protection against corrosion; the cost of blowdown was too high; and the cost on sodium orthophosphate and ligin derivatives (Nalco 728) could be reduced. Recommendations are made based on the test results and plan for future expansion of plant capacity. It is recommended that the …

The effects of temperature on the sensitivity of Daphnia pulex to two simulated industrial effluents
… adult Daphnia pulex to a simulated cooling tower blowdown and a simulated refinery effluent. In addition, the metabolic rate compensation capability of Daphnia exposed to temperature was determined. An artificial refinery mixture (ARM) simulated the 1977 guidelines promulgated by EPA. Components …

Loss mechanisms in a highly loaded transonic axial turbine stage
… The test data has been acquired in a cascade and blowdown turbine research rig. Specifically, the overall loss determined from unsteady three-dimensional flow computations of a cooled one-and-a-half stage turbine is within 6% of that inferred from the blowdown turbine rig test data. The computed …

Experimental study of rapid pressure transients in a two-fluid, two-phase system and comparison to RELAP5
… The two experiments described in this thesis, a blowdown and a pressure surge, are designed to create a fast pressure transient wherein the interfacial behavior between the two fluids can be measured reliably. These measurements are compared against a RELAP5 simulation to support the validity of …
