A multigrid method is presented for calculating turbulent |
|
jets in crossflow. Fairly rapid convergence is obtained |
|
with the k-epsilon turbulence model, but computations |
|
with a full Reynolds stress turbulence model (RSM) are |
|
not yet very efficient. Grid dependency tests show that |
|
there are slight differences between results obtained on |
|
the two finest grid levels. Computations using the RSM |
|
are significantly different from those with k-epsilon |
|
model and compare better to experimental data. Some work |
|
is still required to improve the efficiency of the |
|
computations with the RSM. |
