Also, the additional flow does not come from the primary fluid flow, but
from the ejector nozzle. We want to increase the flow of the primary
fluid (the exhaust gas) so I really don't think ejector theory would
apply in this case.
I suggested ejector theory for our HVAC outlets on the Cadillacs,
but although it offers the promise of increased airflow to the passenger, it
has a few negative effects on HVAC performance.

Ahhh, jeez, now you tell me. I'm _not_ a nerd, OK? :-) Gearhead maybe...
