A thought, maybe not a good one..but perhaps a laminar flow element,
aka LFE would be useful to inject air or gas into the rotor section. A
LFE can simply be made from closely spaced plates - perhaps your
existing plate spacing on your rotor could be used. It works by having
a large channel length to diameter ratio. The renolds number is a
function of the LD ratio, so with smaller channels, laminar flow can be
maintained. Laminar flow elements are often used for flow measurement
devices, as the delta P is linear over awide range of flow. Refer to a
Perry's or Marks handbook to calculate the channel size need for
laminar flow at your mass flow rate.

Some time ago somebody (forgotten who) mentioned, in passing, that hard
drive discs might serve as rotors in a Tesla Turbine.
I had been working for some time on that idea and now I am finally ready to
show the world (or at least RCM) the results.

Click on Tesla Turbine - go figure
The page is still incomplete but the basics are there.

Sincerely.
