Heat and Mass Transfer in Particulate Suspensions on the fundamentals of the transport processes using particle-fluid suspensions, such as nanofluids.

The thermal transport properties of nanofluids, including thermal conductivity, viscosity, heat capacity and heat transfer coefficient in convective environment were characterized and modeled. Obvious thermal conductivity increases have been observed in these nanofluid systems, e.g., 52% enhancement in thermal conductivity was found in water-in-FC72 nanofluids.

Graphene nanoplatelets are also offered in granular form which could be dispersed in water, organic solvents, and polymers with the right choice of dispersion aids, equipment, and techniques. The goals of this dissertation were (i) to investigate the mechanisms behind the thermal conductivity enhancement of nanofluids; (ii) to develop new combined mechanisms based on the analytical thermal conductivity model; (iii) to numerically investigate the fluid dynamics and heat transfer characteristics of nanofluids in a circular tube corresponding to the new analytical thermal conductivity Enhanced thermal conductivity of nanofluids compared to that of the base fluid has received attention of many researchers in the last one decade. Experimental data on thermal conductivity of nanofluids using varied nanoparticles in the size range 10-100 nm have been reported. However, there is lot of variance in the data and needs critical analysis. Several characteristic behaviors of nanofluids have been identified, including the possibility of obtaining large increases in thermal conductivity compared with liquids without nanoparticles, strong temperature-dependent effects, and significant increases in critical heat flux. Observed behavior is in many cases anomalous with respect to the 2005-06-01 · Nanofluids for thermal transport Synthesis of nanofluids.
