Today was spent raising the resolution of the analysis and re-running the
preliminary
solution... Some points of interest were glanced over also being static
pressure inside the engine cowl, flow velocity through various airframe vents
and openings...
Regarding the main gear area... as the images show, with the gear retracted and
set at its operational position, due to the existing lower cowl faring, it
remains
just on the cusp of free-stream air during flight; however, about 80db of
noise is being displayed downstream; whether this is caused by the wheel or
the cowl faring is not yet determined... some updated images attached.
The areas responsible where most noise is generated are the flap tube ports in
the fuselage; somewhere in the order of 90db. However this may alter with the
wings installed.
Next session will be looking at same results while utilising a wheel faring.
