Influence of molecular weight of PVP on aggregation and thermal diffusivity of silver-based nanofluids

Agresti F., Barison S., Battiston S., Pagura C., Colla L., Fedele L., Fabrizio M., National Research Council of Italy (CNR), IT

With the aim of preparing stable nanofluids for heat exchange applications and to study the effect of surfactant on the aggregation of nanoparticles and thermal diffusivity, stable silver colloids were synthesized in water by a [...]

Study on the Heat Transfer Capability of Silicon Carbide – Ethylene Glycol Nanofluid

Bobbo S., Colla L., Scattolini M., Fedele L., Consiglio Nazionale delle Ricerche, IT

Ethylene glycol-based nanofluids containing silicon carbide (SiC) in the concentrations 0.1, 1 and 5 wt% were characterized, in order to understand their potentiality to improve the heat transfer efficiency of the base fluid. Measurements performed [...]

Thermal Conductivity and Viscosity Measurements of Water-Based Silica Nanofluids

Bobbo S., Colla L., Scattolini M., Agresti F., Barison S., Pagura C., Fedele L., CNR-Consiglio Nazionale delle Ricerche, IT

Nanofluids are a new class of fluids that could significantly improve the thermal properties of fluids used as thermal vectors. They are obtained by dispersing in common fluids (water, glycol, oil) solid nanoparticles (diameter <100 [...]
