The case considered is therefore 1d radial laminar flow of a swirling fluid between two rotating porous coaxial cylinders. The analyical solution for the tangential velocity is: U=A/R+B*R** (1.+REYM) where the Reynolds number REYM=VIN*RADI/ENUL and the constants A and B are given by:B=(OMEGI*RADI**2-OMEGO*RADO**2)/ (RADI**(2.+REYM)-RADO**(2.+REYM) and A=OMEGI*RADI**2-B*RADI** (2.+REYM).
