VANT. Ser.: Mat. Mod. Fiz. Proc 2011. Вып.3. С. 16-28.

Described here are explosive combustion and detonation methods implemented in EGAK and TREK codes using fixed grids. Computational results of 2D problems using fixed grids are also given with detonation control programs, two-component model of Tarver kinetics and four-component model of Morozov-Karpenko kinetics. Computations were carried out with adaptive non-integral grid.

Keywords: explosive, detonation, detonation velocity control, initiation time, Huygens principle, adaptive non-integral grid, Tarver kinetics, Morozov-Karpenko kinetics.
