| :Sorry to be such an android. Are you referring to some post I have yet to see? yes.
I can't get my fluid dynamics to work out on my design plenum, the numbers aren't working out. Specifically,
- I can't get anywhere with how many specific CFM our
engines ingest (NA or TT). So I can't plug those numbers in
as my boundary conditions.
- I can't get anywhere on volumetric efficiency numbers
either, cause it's based on CFM. All I know is each turbo, at peak efficiency generates 306
CFM per a fantastic TTnet members website (who I cannot
recall) So, I can make all these pretty stream pictures of flow, but
I can't get anywhere with the rest. When Damon and I did the fuel rails, we had a ton of
constants. We new the pumping efficiencies of the stock
fuel pumps, the delivery rate of the fuel injectors and the
pressure in the fuel line. Everything was defined clearly.
Damon even hired a PE to hand calculate everything, so we
KNEW our numbers were right on. So,... I want to model both intake plenum's using CFD to
give an accurate picture of everything. But if my numbers
aren't real, all I get are pretty pictures with ribbon flow.
