### TITLE : ALGEBRAIC SLIP MODEL - OIL SEPARATION IN A CIRCULAR PIPE

BY : CHAM Consultancy Team - J Heritage

FOR : Demonstration Case

DATE : 1993

PHOENICS VERSION : 2.0

### 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

Pictures are as follows :
