TITLE : FLOW IN A DRILLING BIT

BY : Qihui Zhang - CHAM UK
DATE: 1996

DETAILS:

• The flow around a drilling bit is simulated.

• The simulation is 3D and the geometry is set up using the ASAP procedure.

NOTES ON ASAP:

• ASAP (Arbitrary Source Allocation Procedure) is a PHOENICS add-on solving problems concerning arbitrarily distributed sources and complex geometry in any coordinate system.

• Compared with BFC systems, ASAP can be used for any complex geometry without creating meshes that are difficult to converge.

• ASAP matches the existing geometry with the provided mesh and has been used in a wide range of cases.
