TITLE : ALGEBRAIC SLIP MODEL - OIL SEPARATION IN A CIRCULAR PIPE (PHOENICS Library Case : 110)

BY : CHAM Consultancy Team - J Heritage
FOR : Demonstration Case
DATE : 2022
PHOENICS VERSION : 2022.1

DETAILS :

• Three-Dimensional, Steady-state elliptic simulation
• Polar computational grid

NOTES :

• Calculates the accumulation of two groups of particles of different diameters along the bottom of a circular pipe
• The Algebraic Slip Model is used to solve this problem
• Slip velocities are normal to the continuous phase flow direction
• Larger particles fall to the bottom more quickly than the smaller ones
• This forces the liquid to rise up bringing the smaller particles with it

Geometrical configuration. The geometry has been expanded by a factor of 5 in the radial direction.
