| Abstract: Heat transfer during the slow cook-off test of PBX was successfully simulated using three computational codes. LS-DYNA and COMSOL Multiphysics are both 3D multipurpose commercial codes based on the finite element method. The simplified 1D simulation was carried out using GNU/Octave and the finite difference method. The codes, their applicability for the modeled problem, advantages and disadvantages are discussed and evaluated. The results were compared to the experimental slow cook-off test of Semtex 1A (czech PETN based putty-plastic explosive) and with the critical temperature according to the Frank-Kamenetskii theory. The best agreement between the simulated and experimental value of the ignition temperature was obtained using GNU/Octave script, but COMSOL Multiphysics seems to be better choice due to its accessibility and advantages in this particular case. | ||
