== 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 thikness 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!
