Abstract

Biomimetics is the use of biologically-inspired solutions for engineering applications. In biological systems, hierarchical bifurcating flow passages produce space-filling flow networks, minimize flow resistance, and enhance surface area to volume ratios. These are all desirable characteristics for liquid cooled heat sinks as well as biological systems. Tree-like flow networks have many advantages when compared to traditional parallel-flow networks. Tree-like flow networks have greater surface area for heat transfer per unit volume when compared with traditional parallel flow heat sinks. Other advantages of tree-like flow networks as compared to parallel flow networks include lower total pressure drop as a consequence of pressure recovery at bifurcations as well as lower, more uniform, maximum wall temperatures. Results pertaining to the performance of a biologically-inspired microscale liquid cooled heat sink will be presented. Computationally Fluid Dynamics (CFD) was used to analyze local flow behavior as well as pumping power requirements.
