This work numerically examined effects of nanofluids flow on heat transfer in a C-shaped geometiy with the aim to evaluate potential advantages of using nanofluids in a chaotic flow. Numerical computations revealed that the combination of nanofluids and chaotic advection can be an effective way to improve thermal performance of laminar flows. The results indicated that addition of only 1-3% CuO or Al2O3 nanoparticles (volumetric concentration) to the chaotic flow improved heat transfer by 4-14% and 4-18%, respectively, with a marginal increase in the pressure drop.
