Unstable capillary waves on surface of separation of two viscous fluids

Unstable capillary waves on surface of separation of two viscous fluids

Date: April 1, 1951
Creator: Borodin, V A & Dityakin, Y F
Description: The study of the breakup of a liquid jet moving in another medium, for example, a jet of fuel from a nozzle, shows that for sufficiently large outflow velocities the jet breaks up into a certain number of drops of different diameters. At still larger outflow velocities, the continuous part of the jet practically vanishes and the jet immediately breaks up at the nozzle into a large number of droplets of varying diameters (the case of "atomization"). The breakup mechanism in this case has a very complicated character and is quite irregular, with the droplets near the nozzle forming a divergent cone.

Unsteady oblique interaction of a shock wave with a plane disturbance

Unsteady oblique interaction of a shock wave with a plane disturbance

Date: January 1, 1954
Creator: Moore, Franklin K
Description: Analysis is made of the flow field produced by oblique impingement of weak plane disturbances of arbitrary profile on a plane normal shock. Three types of disturbance are considered: (a) sound wave propagating in the gas at rest into which the shock moves; (b) sound wave overtaking the shock from behind,(The sound wave reflects as a sound wave, and a stationary vorticity wave is produced); (c) an incompressible vorticity wave stationary in the gas ahead of the shock. The incident wave refracts as a stationary vorticity wave, and either a sound wave or attenuating pressure wave is also produced. Computations are presented for the first two types of incident wave, over the range of incidence angles, for shock Mach numbers of 1, 1.5, and infinity.

Uranium Concentration Meter

Uranium Concentration Meter

Date: September 24, 1956
Creator: Arnett, Orville
Description: From abstract; "Two basic instruments were developed for determining the concentration of uranium in solutions. Both instruments detect the gamma activity present in a sample solution, and interpret this analysis into direct presentation as parts per million."

Uranium-Mining Practices and Costs at Ten Salt Wash Lease Operations of Union Carbide Nuclear Co.

Uranium-Mining Practices and Costs at Ten Salt Wash Lease Operations of Union Carbide Nuclear Co.

Date: 1959
Creator: Dare, W. L.
Description: Report issued by the U.S. Bureau of Mines discussing the mining costs and methods of uranium ores in Colorado. As stated in the introduction, "this report describes the relatively small-scale operations of the Salt Wash miner: the mining methods followed, the equipment used, and the production costs" (p. 1). This report includes tables, maps, illustrations, and photographs.
