segregated flow solver
 

please tell me what is meant by segregated flow solver.how it differs from coupled solver. thanks sania

Dear Madam

The segregated solver is the solution algorithm previously used by FLUENT 4. Using this approach, the governing equations are solved sequentially (i.e., segregated from one another). Because the governing equations are non-linear (and coupled), several iterations of the solution loop must be performed before a converged solution is obtained.

The coupled solver solves the governing equations of continuity, momentum, and (where appropriate) energy and species transport simultaneously (i.e., coupled together). Governing equations for additional scalars will be solved sequentially (i.e., segregated from one another and from the coupled set.

Hope this Help. You should see the chapter 24 of Fluent's Manual.

Wasalam Mukkarum
