Hi Rob,
Totally agree with you on the plume resolution, but I've deliberately decreased the resolution on this region to fine-tune the methodology.
The analysis is assumed to be a steady-state of the precise moment when a aircraft gets full power for take-off (just right before start moving).
Monitoring points would be a good idea to check the length of the plume for the given velocities at the exhaust (44, 22 and 15 m/s) during the analysis, thanks.
I'm now running an analysis considering the inlet outside bound as "Velocity Inlet", since I'll need to control the velocity at the inlet to replicate the wind. The outlet ouside bound is set as "pressure inlet", since any other is not performing well. Do you have any other suggestion on the outside bounds?
This is how the residuals are looking now (a bit better I guess):
Thanks!
