HCT: A General Computer Program for Calculating Time-Dependent Phenomena Involving One-Dimensional Hydrodynamics,Transport,and Detailed Chemical Kinetics.

摘要

A general computer program called HCT is described that is designed to calculate time-dependent problems involving one-dimensional gas hydrodynamics,transport,and detailed chemical kinetics. HCT is designed to handle a wide variety of calculations in the framework of a general ''robust''integrator. The difference equations used and the reasoning governing their selection are described in detail. The solution of the difference equation by a generalized Newton's iteration scheme is described. The structure of the coding as implemented on the CDC 7600at Lawrence Livermore Laboratory is explained. An appendix gives a glossary of the variables needed to run problems. A complete listing of the program is given in a second appendix. Several sample problems are described to illustrate the behavior and capabilities of HCT. A comparison with other programs that calculate similar phenomena is given. 14figures, 14tables. (ERA citation 04:008667)
