A numerical study is carried out for analyzing the compressible, non-isothermal flow associated with a separate-flow exhaust nozzle system with conic plug. Within the steady-state Reynolds Averaged Navier-Stokes (RANS) framework, several two-equation turbulence models among which the standard k-epsilon, the standard k-omega, and two different Shear Stress Transport (SST) k-omega formulations are evaluated. In addition, Large Eddy Simulation (LES) approach is employed for capturing the flow dynamics associated with the coaxial jet. The computational results are compared against available experimental Particle Imaging Velocimetry (PIV) flow data, in terms of time-averaged axial velocity and turbulent kinetic energy levels.
