My task is to simulate the crude in the annulas while its pumped from the well. I need to know some information as a background:

1. simulate a vertical pipe 2. define the crude in material database 3. define mixtures in fluent

Also any related information will be highly appreciated.

thank you and hope to see your replys

Dear Nasser,

I just have seen your message and would like to help as i can.

1) Vertical pipe can be defined as an enclosed domain in which you need to define the inlet and outlet boubdaries. remember to activate the gravity as external source.

2) if you know the crude material properties then you can edit it to the existed material database in Fluent program.

Hope this could help
