  Measurement techniques such as Magnetic Resonance Velocimety (MRV) and
Magnetic Resonance Concentration (MRC) are useful for obtaining 3D
time-averaged flow quantities in complex turbulent flows, but cannot measure
turbulent correlations or near-wall data. In this work, we use highly resolved
Large Eddy Simulations (LES) to complement the experiments and bypass those
limitations. Coupling LES and magnetic resonance experimental techniques is
especially advantageous in complex non-homogeneous flows because the 3D data
allow for extensive validation, creating confidence that the simulation results
portray a physically realistic flow. As such we can treat the simulation as
data, which "enrich" the original MRI mean flow results. This approach is
demonstrated using a cylindrical and inclined jet in crossflow with three
distinct velocity ratios, $r=1$, $r=1.5$, and $r=2$. The numerical mesh is
highly refined in order for the subgrid scale models to have negligible
contribution, and a systematic, iterative procedure is described to set inlet
conditions. The validation of the mean flow data shows excellent agreement
between simulation and experiments, which creates confidence that the LES data
can be used to enrich the experiments with near-wall results and turbulent
statistics. We also discuss some mean flow features and how they vary with
velocity ratio, including wall concentration, the counter rotating vortex pair,
and the in-hole velocity.
