A DISCUSSION AND BIBLIOGRAPHY OF CURRENT LITERATURE CONCERNING VAN ALLEN BELTS FOR USE IN SNAP SPACE ENVIRONMENTAL STUDIES

Description: Discussion of theories on particle motion in electric and magnetic fields precedes examination of theories on the source of the inner and outer Van Allen belts. Theories for the inner belt propose solar cosmic ray injection and galactic cosmic ray injection as the source of the protons. Neutron albedo is particularly examined but seems to be unaccountable for the proton belt. Neutron albedo and injection from the sun are also considered as possible sources of the electrons in the outer belt. Fl… more

SNAP Radioisotope Space Programs. Quarterly Progress Report No. 8, Task 7, July 1 Through September 30, 1961

Description: Activities in a program devoted to the safety evaluation of isotopic power systems in space applications are reported. In the study of upper atmosphere re-entry, flare and telemetry test capsules were completed for scheduled re-entry tests. The altitude of re-entry burn-through for all phase I and II test capsules and nose cone-vehicle-pod relative position data were determined. These data were used in determining the optimum positions and headings for the optical and optical-telemetry aircraft… more

HIGH ACCELERATION FIELD HEAT TRANSFER FOR AUXILIARY SPACE NUCLEAR POWER SYSTEMS. Quarterly Technical Report, December 1, 1962-February 28, 1963

Description: The liquid metal heat transfer system that is shortly to be used to investigate fundamental boiling and condensing phenomena in liquid metals was sufficiently completed so that preliminary non-boiling water heat transfer experiments were conducted. The purpose of these studies was to establish the accuracy of the heat transfer instrumentation for the boiler test section, gain operating experience and obtain information on system integrity. Satisfactory heat balances were obtained and experiment… more

THE AXISYMMETRIC FREE-CONVECTION HEAT TRANSFER ALONG A VERTICAL THIN CYLINDER WITH CONSTANT SURFACE TEMPERATURE

Description: Laminar free-convection flow produced by a heated, vertical, circular cylinder for which the temperature at the outer surface of the cylinder is assumed to be uniform is analyzed. The solution of the boundary-layer equations was obtained by the perturbation method of Sparrow and Gregg, which is valid only for small values of the axial distance parameter xi ; and the integral method of Hama et al., for large values of the parameter xi . Heat-transfer results were calculated for Prandtl numbers (… more

On the Transfer of Heat to Fluids Flowing Through Pipes, Annuli, and Parallel Plates

Description: Nusselt numbers were calculated for heat transfer to fluids flowing through annuli under conditions of uniform heat flux and fully established velocity and temperature profiles. The following cases were considered: (a) laminar flow, (b) slug flow, (c) turbulent flow with molecular conduction only, and (d) turbulent flow with both molecular and eddy conduction. These Nusselt numbers were determined for two conditions: heat transfer from the inner wall only and heat transfer from the outer wall o… more

Turbulent exchange of momentum, mass, and heat between fluid streams and pipe wall

Description: S>A new correlation is presented to describe mass and heat transfer to a fluid in a fully developed turbulent flow in a pipe. The correlation differs from earlier empirical relations in that it is based on a theoretical continuous eddy-viscosity distribution from the wall to the center of the pipe. Transfer rates calculated from the new correlation are in excellent agree ment with experimental data on mass and heat transfer to fluid streams. (auth)

Development of salt velocity technique

Description: The salt velocity technique for measuring coolant flow through a SNAP 8 tri-cusp channel was studied and developed. The parameters important in obtaining reproducible data were investigated and a test procedure, which yields dath of good precision, was developed. Dath were taken on a tri-cusp channel with flush circular electrodes (0.125 inch O.D.) as well as on a tri-cusp channel with parallel plate electrodes (0.006 inches thick, 0.250 inches long), which were situated 0.050 inches apart and … more
