Abstract In the present study, the base pressure variations induced by the presence of a cavity, known to have a strong
influence of the behaviour of supersonic projectiles, are investigated through numerical solution of the balance
equations for mass, momentum, and energy. An area ratio of four is considered and numerical simulations
are carried out at Mach M = 1.2, 1.4, 1.6, and 1.8 assuming no cavity or cavity locations 0.5D, 1D, 1.5D, and
2D. The inlet pressure of the nozzle is considered as a flow variable. The Taguchi method is also used, and
the considered cases are then analyzed using… More >
