Class 3 Error

SYMPTOM:
The normal velocity components of child droplets in the CAB and ETAB breakup sub-models of the particle transport model can be slightly incorrect, leading to too great a deflection of a spray. However, other parameters such as spray penetration length are not affected very much.

PROBLEM:
This is due to incorrect use of the drag factor in calculating these normal velocity components: the drag on the child droplets should be used, whereas the code uses the drag on the


WORKAROUND:
No workaround is currently available.

FIXED IN:
ANSYS CFX 11.0 Update 1
