General Theory for Dynamic Instability of the SSME LOX Posts

Description: A general theory of fluid-elastic instability for a tube array in crossflow is presented for application to the space shuttle main engine liquid oxygen (SSME LOX) posts. Various techniques to obtain the motion-dependent fluid-force coefficients are discussed and the general instability characteristics are summarized. The theory is also used to evaluate the results of other mathematical models for crossflow-induced instability.

Fluid Excitation Forces Acting on a Tube Array

Description: Fluid forces are important in the assessment of vibration of the Space Shuttle Main Engine liquid oxygen posts. This report summarizes the available data on fluid excitation forces acting on tube arrays in turbulent crossflow, and test results for an array of tubes subject to turbulent flow. The fluctuating drag and lift forces are measured as a function of Reynolds number, incoming flow conditions, and tube location in an array.

Extraction and Recovery of Plutonium and Americium from Nitric Acid Waste Solutions by the TRUEX Process : Continuing Development Studies

Description: This report summarizes the work done to date on the application of the TRUEX solvent extraction process for removing and separately recovering plutonium and americium from a nitric acid waste solution containing these elements, uranium, and a complement of inert metal ions. This simulated waste stream is typical of a raffinate from a tributyl phosphate (TBP)-based solvent extraction process for removing uranium and plutonium from dissolved plutonium-containing metallurgical scrap. The TRUEX pro… more

Chemical and Biological Characterization of Black Rock Harbor Dredged Material

Description: "This is one in a series of scientific reports documenting the findings of studies conducted under the Interagency Field Verifications of Testing and Predictive Methodologies for Dredged Material Disposal Alternatives (referred to at the Field Verification Program or FVP). This program is a comprehensive evaluation of environmental effects of dredged material disposal under conditions of upland and aquatic disposal and wetland creation."
