A theoretical approach of the heat transfer in nanofluids

Abstract

Using the fractal space-time theory (scale relativity theory), the dynamics of the fluid/nano-particle interface was analyzed. In the general case, the heat transfer through the interface reproduces a d.c. or an a.c. Josephson effects of thermal type, while in the linear approximation, the standard form of heat transfer is given. Consequently, a negative differential thermal conductance appears and an increase in of heat transfer in nanofluids results. © 2007 The Japan Institute of Metals.
