The unsteady compressible flow around a 50
mm projectile governed by the Navier-Stocks (NS) equation is numerically solved
with a Large Eddy Simulation (LES) method, with the Sub-Grid Scale (SGS) solved
by Smagorinsky-Lilly model. The computed results are obtained in supersonic
flow regime for a viscous fluid in order to determine the aerodynamic
coefficients with different angles of attack. The flow around a body tail
projectile was solved as a three-dimensional flow.
