Summary: | This paper presents a computational fluid dynamics analysis of the delayed detached eddy simulation–shear-stress
transport on a 1:16 scale simplified C-130H fuselage model in flight conditions and with a closed cargo ramp to
observe the turbulent-flow structures that evolve behind its empennage region. The results of which are also
compared against already existing x-vorticity plots of the delayed detached eddy simulation–Spalart–Allmaras with
rotation and curvature correction. With vorticity magnitude of 750 rotations∕s, the delayed detached eddy
simulation–shear-stress transport is shown to display a lot more detail in terms of the formation and unsteadiness of
the upsweep and detached vortices. The simulations are performed with the finite volume solver Cobalt with up to 64
processors on a high-performance computer. |
