Shaft
For optimizing flow, the exaust ports are integrated in the shaft. The convex cone should redirect the flow properly.
Discs
as the gap size depends on kinematic viscosity, entrance speed of the fluid and the relative disc diameter, its better to use a trapezoid profile for the discs. The laminar boundary thickness could be better used. Therefore friction should raise. This was inspired by the formula
<math>
x = 5 {\sqrt{v * l /u}}
x: gap Size
v: kinematic viscosity
l: relative disc diameter (Rmax - Rmin)
u: entrance Speed
</math>
Inlet Port
Using static orifice discs around the rotor has shown better results, both in simulation and testruns. The orifice profile in the pictures is just for illustration and not optimized, yet!
