Hydrides and Metal-Hydrogen Systems. Final Report

Description: The work reported deals with the preparation and physical properties, especially thermal dissociation pressures, and densities of hydrides, hydrogen- metal systems, and mixtures of hydrides with other substances. Possible applicatlons as moderators, high-temperature neutron shields, and low-temperature shields are cited and design problems discussed. Most of the data on dissociation pressures cover ranges and compounds not hltherto explored because of experimental difficulties and the basic kno… more

Electrical Resistivity Investigations of Carnotite Deposits in the Colorado Plateau

Description: From abstract: An investigation of the use of geophysical methods in prospecting for carnotite deposits in the Colorado Plateau was made by the Geophysics Branch of the U. S. Geological Survey between April 21 and June 24, 1949. Results of this preliminary work indicated that electrical resistivity methods could be used successfully.

{open_quotes}O{close_quotes} ring sealed process tube, Phase II, test project

Description: The {open_quotes}O{close_quotes} ring seal has been proposed to replace the van stone flange and the bellows thermal expansion assembly currently used on the existing Hanford piles to achieve water and gas seals, respectively. Possible advantages of the {open_quotes}O{close_quotes} ring seal are: (1) simplification of component parts and elimination of van stone corrosion; (2) simplification of maintenance; (3) lower costs of initial erection; (4) increased strength. This test supplements Test … more

Energy Doubling in D.C. Accelerators

Description: It is generally believed that charged particles cannot be accelerated from ground potential to ground potential unless they pass through a system which has associated iwth it a time varying magnetic field. D.C. electric fields must satisfy the equation {contour_integral} Eds = 0, while the time varying fields used in radio-frequency accelerators and betatrons are freed from this restriction of scalar potential theory. In 1932, AJ Dempster produced protons with an energy of 45 Kev, by passing th… more

Survey of Processing Methods for the Production of Thorium Metal from Monazite Sand and Thorium Nitrate

Description: Cost estimates for two types of Th producing plants are offered. One utilizes Th(NO3)4 as raw material, the other uses monazite sand. Final processing schemes and plant designs are not fixed, so the estimates represent maximum costs. Recommendations for research and development of Th producing methods are given.

Effect of tail surfaces on the base drag of a body of revolution at Mach numbers of 1.5 and 2.0

Description: "Wind-tunnel tests were performed at Mach numbers of 1.5 and 2.0 to investigate the influence of tail surfaces on the base drag of a body of revolution without boattailing and having a turbulent boundary layer. The tail surfaces were of rectangular plan form of aspect ratio 2.33 and has symmetrical, circular-arc airfoil section. The results of the investigation showed that the addition of these tail surfaces with the trailing edges at or near the body base incurred a large increase in the base-… more

A numerical approach to the instability problem of monocoque cylinders

Description: Report presenting two closely related methods which employ operations tables that have been developed and used in the calculation of buckling load of a monocoque cylinder subjected to pure bending. The buckling loads of three cylinders with very different characteristics were calculated using the methods.

Method for determining pressure drop of monatomic gases flowing in turbulent motion through constant-area passages with simultaneous friction and heat addition

Description: Report presenting charts that enable convenient determination of the pressure drop sustained by monatomic gases flowing at high subsonic speeds in a constant-area passage under the simultaneous influence of friction and heat addition. Pressure drops are determinable with good accuracy for other modes of heat addition using an effective wall temperature in conjunction with the charts. The effective wall temperature is given in terms of the passage dimensions, gas-flow conditions, and gas-tempera… more

Fluctuations in a spray formed by two impinging jets

Description: Report presenting an investigation of the spray resulting from the impingement of two jets of water in order to determine the characteristics of the instability associated with that method of spray formation. A ruffled sheet of liquid was found to form perpendicular to the plane of the two jets. The ruffling of the sheet was found to persist until the sheet disintegrated and established the frequency of wave formation.

On the second-order tunnel-wall-constriction corrections in two-dimensional compressible flow

Description: From Summary: "Solutions of the first- and second-order Prandtl-Busemann iteration equations are obtained for the flow past thin, sharp-nose, symmetric, two-dimensional bodies in closed channels. With the use of these solutions an expression is derived from the tunnel-wall interference. The tunnel-wall correction for a parabolic-arc airfoil is calculated to indicate the effects of compressibility, ratio of the tunnel height to the airfoil chord, and airfoil thickness coefficient."

An experimental investigation of the effect of surface heating on boundary-layer transition on a flat plate in supersonic flow

Description: Report presenting wind-tunnel testing to investigate the effect of surface heating on boundary-layer transition on a flat plate. The identification of the onset and end of transition was made by inspection of the curves of surface-tube Mach number reading as a function of length Reynolds number obtained through the transition region.

Preliminary Investigation of a New Type of Supersonic Inlet

Description: "A supersonic inlet with supersonic deceleration of the flow entirely outside of the inlet is considered. A particular arrangement with fixed geometry having a central body with a circular annular intake is analyzed, and it is shown theoretically that this arrangement gives high pressure recovery for a large range of Mach number and mass flow and therefore is practical for use on supersonic airplanes and missiles. For some Mach numbers the drag coefficient for this type of inlet is larger than … more
