Velocity profiles for infinite cylindrical journal bearing, using small eccentricity perturbation calculation and modified Reynolds number as parameter
Transition region of hypersonic boundary layer on flat plate surveyed with hot wires, giving analysis for limited wire calibration
Neutron gamma activation methods for determining chemical composition of soil samples
Fast and thermal reactors for nuclear rockets noting high temperature materials requirements, performance and low power
Highly negative Langmuir probes effects on electrostatic waves propagation, absorption and reflection below ion plasma frequency
Etiology of neonatal mortality in rats bred and raised at 3,800 meters from low-land parents
Experimental and analytical study of water heat pipes for 200 to 350 deg F temperature range
Tabulation of photographic and photoelectric spectrophotometrically obtained relative spectral line intensities for planetary nebula IC 5217, discussing interstellar absorption
Heat pipe is used in the primary heat exchanger for nuclear power plants, as a heat sink for high-power electronic devices, and in a closed-cycle heat rejection mechanism for cryogenic storage tanks. It serves simultaneously as a heat transfer device and as a structural member.
Analytical framework for viscous and chemically reacting plume
Photometric and spectrophotometric measurements in space astronomy
Computer program for resolution band model prediction of heat transfer from rocket exhaust plumes
Halophilic bacteria growth in freeze-thaw environment, investigating cooling and warming rates and solute concentrations
AISI 52100, a high carbon chromium steel, has the longest fatigue life of eight bearing materials tested. Fatigue lives of the other materials ranged from 7 to 78 percent of the fatigue life of AISI 52100 at a temperature of 340 K (150 F).
