Threfore, the case considered is 1d radial laminar flow of a swirling fluid between two porous coaxial cylinders of radius RADI and RADO, the outer one of which is rotating with an angular velocity of OMEGO and the inner one with angular velocity OMEGI. This case provides, for NX > 1 and RINNER>0, a test of the U1 equation for: radial convection and diffusion; cyclic boundary conditions; wall friction; and coriolis forces. 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).
