The use of symbolic computation in radiative, energy, and neutron transport calculations. Technical report, 15 August 1992--14 August 1994
Abstract
This investigation uses symbolic computation in developing analytical methods and general computational strategies for solving both linear and nonlinear, regular and singular, integral and integro-differential equations which appear in radiative and combined mode energy transport. This technical report summarizes the research conducted during the first nine months of the present investigation. The use of Chebyshev polynomials augmented with symbolic computation has clearly been demonstrated in problems involving radiative (or neutron) transport, and mixed-mode energy transport. Theoretical issues related to convergence, errors, and accuracy have also been pursued. Three manuscripts have resulted from the funded research. These manuscripts have been submitted to archival journals. At the present time, an investigation involving a conductive and radiative medium is underway. The mathematical formulation leads to a system of nonlinear, weakly-singular integral equations involving the unknown temperature and various Legendre moments of the radiative intensity in a participating medium. Some preliminary results are presented illustrating the direction of the proposed research.

The partial snake experiment at the AGS. Progress report, 15 August 1992--14 August 1994
In the two year funding period from August 15, 1992--August 14, 1994, the authors progresses can be summarized as follows: (1) the solenoidal partial snake was installed in the AGS synchrotron in May, 1993 and was subsequently successfully tested; (2) the internal polarimeter for the AGS was assembled, tested and installed in the AGS; (3) the 200 MeV polarimeter at the LINAC was tested; (4) the AGS polarized ion source was renovated; (5) the first phase of the polarized beam experiments was successfully accomplished in April 1--8, 1994, of polarized proton acceleration up to G{sub {gamma}} {approx} 20; (6) theymore » -
Computational fluid dynamics and combustion dynamics. [Annual] progress report, August 15, 1992--February 14, 1994
Research efforts this year concentrated on automatic geometry definition for Cartesian grid calculations in 3D, including a CAD interface, and development of a parallel compressible adaptive AMR in a data parallel environment also in 3D. Effort is still on conservative interface conditions for overlapping meshes. -
Accelerated line-by-line calculations for the radiative transfer of trace gases related to climate studies. Progress report No. 1, 15 September 1993--14 September 1994
In the present study we are studying the effects of including carbon dioxide, ozone, methane, and the halocarbons in addition to water vapor in the radiating atmosphere. The study has focused on two principal issues: the effect on the spectral fluxes and cooling rates of carbon dioxide, ozone and the halocarbons at 1990 concentration levels and the change in fluxes and cooling rates as a consequence of the anticipated ten year change in the profiles of these species. For the latter study the water vapor profiles have been taken as invariant in time. The radiative line-by-line calculations using LBLRTM (Line-By-Linemore »
