Heat Transfer through Near-field Interactions in Nanofluids
Using the Landauer-Buttiker theory we calculate the thermal conductance associated to plasmons modes in one dimensional arrays of nanoparticles closely spaced in a host fluid. Our numerical simulations show that the nearfield interactions between particles have a negligible effect on the thermal conductivity of nanoparticles colloidal solutions (nanofluids). PACS: 65.20.+w, 61.46.+w, 65.80.+n, ...
متن کاملHeat transfer between nanoparticles: Thermal conductance for near-field interactions
We analyze the heat transfer between two nanoparticles separated by a distance lying in the near-field domain in which energy interchange is due to the Coulomb interactions. The thermal conductance is computed by assuming that the particles have charge distributions characterized by fluctuating multipole moments in equilibrium with heat baths at two different temperatures. This quantity follows...
متن کاملNanofluids for Heat Transfer Enhancement – A Review
A nanofluid is a dilute liquid suspension of particles with at least one critical dimension smaller than ~100 nm. Research works so far suggest that nanofluids offer excellent heat transfer enhancement over conventional base fluids. The enhancement depends on several factors such as particle shape, particle size distribution, volume fraction of nanoparticles, temperature, pH, and thermal conduc...
متن کاملStable states in the radiant heat transfer of the near field for two parallel slabs
In this paper, we study the dynamics of the radiative heat transfer of between two slabs. In these systems, depending on the type of slabs and the thermal interaction they have with their surroundings, they can have one or several stable states in the phase space. It can be seen that in these systems, quantities such as distance and thickness affect the states of these systems. We show that the...
متن کاملHeat transfer augmentation in nanofluids via nanofins
Theoretical results derived in this article are combined with experimental data to conclude that, while there is no improvement in the effective thermal conductivity of nanofluids beyond the Maxwell's effective medium theory (J.C. Maxwell, Treatise on Electricity and Magnetism, 1891), there is substantial heat transfer augmentation via nanofins. The latter are formed as attachments on the hot w...
