abstract = {Large-eddy simulations (LESs) of a helicopter engine jet
and an axial fan are performed by using locally refined
Cartesian hierarchical meshes. For the computations a
high-fidelity, massively parallelized solver for
compressible flow is used. To verify the numerical method, a
coaxial hot round jet is computed and the results are
compared to reference data. The analysis is complemented by
a grid convergence study for both applications, i.e., for
the helicopter engine jet and the axial fan. For the
helicopter engine jet, additional computations have been
performed for two different nozzle geometries, i.e., a
simplified nozzle geometry that is consisting of a center
body and divergent outer annular channel, and a complete
engine nozzle geometry with 4 additional struts were used.
The presence of the struts results in a different potential
core break-down and turbulence intensity. Furthermore, for
the axial fan configuration, computations have been
performed at two different volume flow rates. The reduction
of the volume flow rate results in an interaction of the
tip-gap vortex with the neighboring blade which leads to a
higher turbulent kinetic energy near and inside the tip-gap
region.},
