Abstract

An adaptive finite element method for a numerical parametric study is presented to simulate shockinduced combustion with a variation in freestream conditions and projectile radii. The three cases have been simulated for Machs 4.18, 5.11, and 6.46 with a projectile diameter of 15 mm. Machs 4.18 and 5.11 show an unsteady reaction front, whereas Mach 6.46 represents a steady reaction front. However, Mach 4.18, the case for the Mach number below the Chapman-Jouguet can also lead to a stable reaction front by reducing radius of the projectile. Thus, Chapman-Jouguet speed and the projectile radius are crucial factors for the instabilities to trigger.
