Analysis of Laser-Supported Detonation Waves and Laser Beam Propagation in Two Dimensions.

摘要

It is shown that the Flux-Corrected Transport (FCT) algorithm correctly computes the propagation velocity and Chapman-Jouguet pressure for a laser-supported detonation (LSD) wave, even for zone size large compared to the radiation absorption length. A two-dimensional FCT computer program for analysis of LSD wave propagation phenomena is presented. A trajectory method for analysis of two-dimensional laser beam propagation in the paraxial Fresnel approximation, with continuously varying refractive index, is described. (Author)
