Key features of nanofluids that have been reported so far include thermal Flow, convection, and Experiments have shown that nanofluids were able to enhance the thermal conductivity and convective heat transfer by large margins [1][2][3][4], and critical heat flux by up to 300% [5][6][7]. Recent experiments on nanofluids have indicated significant increases in thermal conductivity compared with liquids without nanoparticles or larger particles, strong temperature dependence of This thesis is constructed around the topic of thermal transport in nanofluids, with special emphasis of boiling heat transfer. Nanofluids boiling, as it is popularly known, have been researched nearly for two decades. While some controversies surrounding the boiling mechanisms had been sorted out, others still remained.

The thermal transport mechanisms in nanofluids were further discussed, and the promising approaches for optimizing the thermal conductivity of nanofluids have been proposed. Although various conjectures have been proposed to explain the abnormal increase in thermal conductivity of nanofluids, the detailed mechanism has not been fully understood and explained.
