Thermal Management of Micro/Nano Systems

This research focused on the next generation packaging, Single Level Integrated Module (slim). Previous studies were performed in two-dimensional and three-dimensional modeling of slim. The fine features of slim were modeled utilizing the extensive computing resources provided by the Supercomputing Institute. The features were expected to get finer and the enhanced computing power of the supercomputer is expected to solve this problem.

This group also used supercomputing resources to create a compact model of heat sinks. Inspiration for the current research derives from a possibility for modeling a detailed heat sink when treated as a porous block. The huge decrease in computational time in the compact model was the inspiration for this project. Icepak is the computational fluid dynamics tool used for modeling the compact heat sink model.

Another area of research concerned analysis of deoxyribonucleic acid (DNA) substrate’s thermal behavior by using numerical approach. The numerical result was compared to experimental results, and the substrate’s thermal profile was analyzed by ansys.

Further research is underway reviewing analytic expressions for heat transfer in natural convection from isothermal rectangular plates at various angles of inclination. Correlations are available which deal with both horizontal and vertical configurations, as well as recommended approaches for modifying the correlations to deal with inclined plates. The research group used Supercomputing Institute resources to conduct a numeric study of inclined plates in natural convection to examine the range of angles where the modified vertical and horizontal correlations are applicable.
