Title Confined space containing aluminum explosives field thermal effects of numerical simulation
Abstract: Numerical Simulation of the thermal effects of the blast field is still insufficient, most of the research focus is still the numerical simulation of the explosion pressure field.Numerical simulation was performed to study the internal blast loading of flat-plate explosion chamber with closed end (L/D=1) by AUTODYN, and the rule of inner blast flow field and temperature field were gained.And simulated values with the literature test values were compared.The simulation results show that the considered burning effect in explosive detonation within a certain time uniform by adding more consistent with the simulation results and experimental values of energy release.Finally, simulation results are summarized, and made useful conclusions on the future generations to study.
Key words: explosion chamber; aluminized explosive;numerical nimulation; temperature field;afterburner effect
