Constructal allocation of nanoparticles in nanofluids

We perform a constructal design of heat conduction in a blade-configured disk-shaped domain with uniform heat generation and periphery heat-sink by introducing a transition line from two-path conduction to one-path conduction in the domain. This orderly arranged blade configuration can offer significantly smaller constructal overall temperature difference than that of the dispersed configuration and thus performs much better. The constructal allocation of nanoparticles inside the base fluids and thus the heatconduction design inside the nanofluids are very important for better system performance. This work shows that the search for heat-flow configuration is a key to performance, and the constructal theory is the strategy for discovering the configuration and the significantly better performance.
