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.

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>
