Inference:

From the simulation of shock tube, we came to conclude with lot of information thorugh the simulation. The use of Adaptive mesh refinement increased the cell count during the simulation when AMR is active. As this is Transient state simulation we simulated for 0.003 seconds. We can also simulate for longer time to study the shock inside the tube for longer time. This shock tube simulation is helpful understand the shocks and its aftermaths inside a closed and refined region.
