Definitions

  • an expansion station is made up of a large number of elements (filters, expansion chamber, control valves, meter, etc.). For practical reasons, we seek to reduce the total size.
  • the shape of the main part concentrates the speed profile in the central zone in the vicinity of the axis A maintaining the rate of turbulence in the vicinity of the central axis of the order of 4%.
  • the fluid crosses the main part and acquires, as it passes, velocity components perpendicular to the wall crossed, which achieves the desired effect at a distance downstream of the rectifier which depends on the geometric parameters of the main part such as the curvature of the surface and the inclination of a generator with respect to the axis A.
  • FIGS. 5A and 5B respectively represent in section and in perspective an advantageous embodiment because it is simple to carry out.
