The pipe-work considered is 2 m in length; the radius at inlet is 0.15 m; it diminishes to a minimum of 0.09 m in front of the ball; and the maximum radius is 0.16 m. A plug profile of axial velocity is prescribed at the inlet, and a fixed-pressure condition is employed at outlet. Wall friction is activated along the boundary of the ball, and along the pipe wall. A fixed turbulent kinematic viscosity is set to 100 times the laminar value (the Reynolds number is of order 1.0E5). ENDDIS ************************************************************ Group 1.
