Linearized Three Component Magneto-Hydrodynamics

Description: "A linearized three component MHD theory is given. The three components are two oppositely charged species and a neutral species. Linearized macroscopic equations are presented which in the limit of vanishing magnet field reduce to fluid dynamical equations, and in the limit of vanishing neutral components is frictional. In addition the sound speed that enters is a function of three equilibrium densities. These equations yield a dispersion relation which is tenth order in the wave speed. The d… more

Linkage in Autotetraploids and Allotetraploids of Zea

Description: Studies of linkage in polyploids have been exceedingly rare. Only three previous studies of linkage in autotetraploid maize have been reported. Murray (1944), in a limited analysis of crossing over among 4 linked markers in chromosome 2, found varying degree of difference in linkage values between 2n and 4n maize in the three interposed segments. Dempsey (1956) found linkage values wx - c region of chromosome 9 to correspond closely between autotetraploid and diploid maize. More recently Welch … more

LINPACK Working Note #3: Fortran BLAS Timing

Description: This working note examines different Fortran implementations of the Basic Linear Algebra Subprograms (BLAS). Since the BLAS will be used to carry out the main computation in many applications, an efficient implementation is necessary. Tests are run on 24 different computers to determine which implementation gives the best performance.

LINPACK Working Note #13: Implementation Guide for LINPACK

Description: This working note is intended to help a person install and test LINPACK. The instructions are designed for a person whose responsibility is the maintenance of a mathematical software library. It is assumed that the reader has a working knowledge of the system job control language and some experience with numerical calculations. The installation process involves reading a magnetic tape, creating a library from the Fortran source, then running and examining the output of the test aids.

LINPACK Working Note #15 : LINPACK, a Package for Solving Linear Systems

Description: The design, development, and use of the software package called LINPACK, a collection of subroutines to solve various systems of simultaneous linear algebraic equations are described. The package has been designed to be machine-independent and fully portable and to run efficiently in many operating environments.

Liquefaction of air in the Langley 11-inch hypersonic tunnel

Description: Report presenting pressure and scattered-light measurements in the 11-inch hypersonic tunnel to determine the effect of stagnation temperature on the flow in two Mach number 7 nozzles and to determine the nature of the condensation process occurring at low stagnation temperatures. Results regarding the static-pressure measurements, Mach number effect, particle size and concentration, and general discussion are provided.

Liquid Cooling of Aircraft Engines

Description: This report presents a method for solving the problem of liquid cooling at high temperatures, which is an intermediate method between water and air cooling, by experiments on a test-stand and on an airplane. A utilizable cooling medium was found in ethylene glycol, which has only one disadvantage, namely, that of combustibility. The danger, however is very slight. It has one decided advantage, that it simultaneously serves as protection against freezing.

Liquid-Liquid Contact in Vapor Explosion

Description: The contact of two liquid materials, one of which is at a temperature substantially above the boiling point of the other, can lead to fast energy conversion and a subsequent shock wave. This phenomenon is called a vapor explosion. One method of producing intimate, liquid-liquid contact (which is known to be a necessary condition for vapor explosion) is a shock tube configuration. Such experiments in which water was impacted upon molten aluminum showed that very high pressures, even larger than … more

Liquid-Liquid Extraction

Description: Abstract: "Extraction equipment of the multistage mixer-settler type has been found useful for providing the intensive contact between phases that is required in processes involving complex compounds of the heavy metals. In this report, the factors of mixer-settler design and operation are discussed with reference to the known types of mixer-settler units. Following this review, a detailed description is given of mixer-settler units constructed and installed in this laboratory."

Liquid Magnesium as a Coolant for Thermal Reactors

Description: It was suggested to the writer by K.A. Eschbach that liquid magnesium might offer certain advantages as a reactor coolant. As a result of this suggestion, a preliminary investigation of the possibilities of this material was made. Definite advantages for a restricted class of applications were found, but a detailed evaluation would seem to require further basic experimental research on the heat transfer, corrosion and flux-mechanical properties of the substance.
