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.
