Detached Eddy Simulations of a Reaction Control Jet from an Axi-Symmetric Body in a Supersonic Crossflow
The introduction of a control jet into a supersonic cross flow yields a substantial region of separated flow, manifesting in the vicinity of the injection site. This, in turn, alters the distribution of pressure on the primary body, thereby influencing the effectiveness of the injected jet’s capa...

| description | The introduction of a control jet into a supersonic cross flow yields a substantial
region of separated flow, manifesting in the vicinity of the injection site. This, in
turn, alters the distribution of pressure on the primary body, thereby
influencing the effectiveness of the injected jet’s capacity to produce the desired
control forces and moments. In the context of an axi-symmetric parent body, this
disruption typically leads to a reduction in effectiveness, owing to the overflow of
the shock structures encompassing the parent body. The present study
investigates the injection of a reaction control jet into a supersonic crossflow
using different Detached Eddy Simulation (DES) techniques. The side jet is
injected from an orifice on an axi-symmetric parent body, which is aligned with
the crossflow direction. The effects of the side jet on the flow field are analysed
in terms of general flow features and spectral behaviour of pressure and
turbulent kinetic energy. The DES results are compared with those obtained from
RANS using various turbulence models. The overall effect of a transient
interaction pulse is characterized using URANS and two different DES models. |
