A Zonal Decomposition Methodology for Detailed Temperature Field Evaluation
M. Pecht and C.H. Tan
A zonal decomposition technique is developed for temperature field and
flux determination at both aligned and non aligned grid interface boundaries.
The method facilitates heat transfer problems commonly encountered in electronics
including PWBs with multiple irregular boundaries in which numerical generation
of boundary-fitted coordinates is required. To demonstrate the applicability
and performance of the method, a 2-D heat conduction problem in Cartesian
coordinates, a 2-D heat conduction problem in curvilinear coordinates,
and a 3-D heat conduction problem in curvilinear coordinates are solved.
Comparisons between numerical and analytical results are shown to be in
