Determination of the packing fraction of silica nanoparticles from the rheological and viscoelastic measurements of nanofluids

Experimental investigation on thermal properties of silver nanofluids

“…The potassium salt was helpful in balancing the pH value of the liquid and dissolving the solutions of fat oil catalysis interaction with hydrogen. Thus, the OAK + has the ability to span the NP's random motion throughout the deionized water (Chiu et al, 2008;Moghaddam et al, 2013;Molchanov et al, 2005;Mondragon et al, 2012;Parametthanuwat, 2012). The rheology measurement results are shown in Fig.…”

Influence of bound water layer on the viscosity of oxide nanopowder suspensions

“…If the flow units were considered as agglomerates rather than individual particles, then [η] becomes a function of interparticle forces. 57,58,[64][65][66] At high solids content, agglomeration is inevitable. Because of the voids in agglomerates, the intrinsic viscosities were expected to be higher.…”

“…K-D equation is a semi-empirical relation whose validity was proven for micron-size powder suspensions for a broad range of solids content. Previously, solids content parameter, Φ, was expressed as effective solids content, Φ eff , to reflect contribution of steric, 42,56 electrical double layer, EDL, 42,57,58 or swelling of the particles 30,59 to the solids content. Similarly, as bound water cannot serve as a solvent in the system, existence of bound water layer amplifies the effect of the solids content on viscosity, especially in nanopowder systems.…”

Rheological properties and thermal conductivity of AlN–poly(propylene glycol) suspensions

“…It has been previously studied and discussed that thermal conductivity of PPG 2000 liquid is moderate and slightly increases with temperature [8,14] (Fig. 9).…”
