This test case is representative of the more generic class of problems involving detonation initiation due to hypersonic projectile behaviour and considers a mechanical stimulus by the impulsive motion of a rigid cylinder which leads to the formation of a detonation wave. Computations are performed on a two-dimensional channel with domain boundaries −0.5
The animation of the pressure contours shows that a high pressure/temperature zone starts developing ahead of the cylinder. When the reaction zone which grows as a result of the temperature rise couples with the shock front, a detonation is formed. The detonation cells of the cylinderically diverging front is clearly noticeable from the schlieren animation.
