Source term integration; Upwind scheme

technocrat.prakash · March 17, 2009, 18:44

Dear friends,

Like to know how to do the integration of the Temperature term "T" term in the governing equation.

Please go through the attachment for problem description and the CFD code.

Thanks in advance.

You can use some quadrature rules for multi-dimensional integration, or a simply mid-point rule.

so in the fvm method,
1, you'd better to write the governing equations in a conserved form, so it will be mor clear to you.
2. integrated T, just use
T*volume of the cell
that ok.

Thanks guys. Let me check whether its working.
