This tutorial illustrates how to set up and solve a periodic heat transfer problem, given a pre-generated mesh.
The system that is modeled is a bank of tubes containing a flowing fluid at one temperature that is immersed in a second fluid in cross flow at a different temperature. Both fluids are water, and the flow is classified as laminar and steady, with a Reynolds number of approximately 100. The mass flow rate of the cross flow is known and the model is used to predict the flow and temperature fields that result from convective heat transfer.
This tutorial demonstrates how to do the following:
• Create periodic zones.
• Define a specified periodic mass flow rate.
• Model periodic heat transfer with specified temperature boundary conditions.
• Calculate a solution using the pressure-based, pseudo-transient, coupled solver.
• Plot temperature profiles on specified isosurfaces.
