PCBCAT Thermal Model

The depth-averaged flow field is used in the solution of the three-dimensional energy equation in the fluid layer and in the electronic devices. By solving the conjugate heat transfer problem the need to specify a heat transfer coefficient is eliminated. The depth-averaged flow field, however, lacks information about the vertical velocity component, and the vertical variations of the velocity components parallel to the plane of the circuit board. This information is provided by models derived from fully-developed flow.
