文档介绍:Tutorial: Solving a Conjugate Heat Transfer Problem using
ANSYS FLUENT
Introduction
The physics of conjugate heat transfer mon in many engineering applications, includ-
ing heat exchangers, HVAC, and ponent design. The purpose of this tutorial
is to provide guidelines and mendations for setting up and solving a conjugate heat
transfer problem using ANSYS FLUENT.
The geometry and flow domain consists of a flat circuit board with a heat generating elec-
tronic chip mounted on it. Heat is conducted through the source (chip) and the board on
which it is mounted. A laminar stream of air flows over the board and the chip, causing si-
multaneous cooling of the ponents and heating of the air stream due to convection.
Thermal energy is also transported due to plex flow field.
This tutorial demonstrates how to do the following:
• Set up appropriate boundary conditions for a conjugate heat transfer simulation in
ANSYS FLUENT.
• Enable source terms for specified zones.
• Perform flow and energy calculations using various materials (both solid and fluid).
• Manipulate mesh adaption registers and perform Boolean operations on them.
• Perform mesh adaption and verify that the solution is mesh independent.
Prerequisites
This tutorial assumes that you are familiar with the ANSYS FLUENT interface and that
you have a good understanding of the basic setup and solution procedures. Some steps will
not be shown explicitly.
You will perform postprocessing related only to mesh adaption and verification of a mesh
independent solution. For detailed postprocessing of this simulation, refer to the ANSYS
FLUENT 13 Tutorial Guide.

Solving a Conjugate Heat Transfer Problem using ANSYS FLUENT
Problem Description
The problem considered is shown schematically in Figure 1. The configuration consists of
a series of heat-generating electronic chips mounted on a circuit board. Air flow, confined
