I assume P-ports here
and 6,000 rpms.

  Namely the intake
port is open 270 degrees.  I guess we have to define 'open'  partial
or fully open and closed.   Doug in Japan.

Hi Doug and George,
I am having trouble seeing a P port ever being closed.
The only event I see is an apex seal passing over the port, a rotor
face moving away with a full charge and a new rotor face being exposed
to the incoming charge.
Maybe a pulse as the flow changes in velocity but no real interruption
of flow or port closing per se; is this not why the VE is so high with
PPs?
This is not the case in a side port, where the passing rotor side wall
closes off the port for a portion of the cycle.
How do you see it?
