TITLE : PARTICLES THROUGH A BALL VALVE (LIBRARY CASE G205)
BY : CHAM Consultancy Team
- The incompressible, single-phase flow of water through a
fully-open axi-symmetric ball valve is solved. The pipe-work
considered is 2 m in length; the radius at inlet is 0.15 m; the
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.
- Particles of different sizes and velocities are introduced
at the valve inlet with several initial velocities.
Pictures are as follows :
