Comparison of turbulence models in near wake of transport plane C-130H fuselage

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 re...

description 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.
