“…If van der Waarden's viscosity data are plotted as Trel against l/am several straight lines are obtained, their gradients (G) depending on the particle size for each particular series of emulsions. When G is plotted against particle size, and compared with similar data for monodisperse latex systems of similar particle sizes (Saunders, 1961), in which no electroviscous effect was observed, it is found that the two sets of data agree fairly closely (Fig 5). With two possible exceptions, the change in Trel for van der Waarden's emulsions is about that anticipated from the variation in particle size (Sherman, 1963~).…”

“…Saunders (1961) also observed this dependence of H on particle size in monodisperse latexes with particle sizes less than lp. His values for H ranged between 1.118 and 1.357: the constant a was unaffected by particle size, retaining a value of 2.504 provided the thickness of the emulsifier layer was allowed for when calculating 4.…”

“…The variation in b probably arises from differences in the particle sizes of the various systems studied. When 4 exceeds 0.05 hydrodynamic interference takes place between the particles, the magnitude of the effect depending on particle size (Saunders, 1961). Waarden (1954) .…”

“…The above formulation was verified by experimental data 10,11) using water and polystyrene latex-particles with a diameter of 0.1 to 1:12Â10 À6 m. The applicability of Eq.

In order to model the mobility of the postulated disrupted core in a core disruptive accident of a liquid metal faster reactor and to provide data for the verification of a reactor safety analysis code (SIMMER-III) a series of experiments was performed to simulate the behavior of a solid particle bed in a liquid pool against pressure transients. Experimental analyses using the SIMMER-III code show that physical models and methods used in the code can reasonably represent the transient behaviors of pool multiphase flows with rich solid phases as observed in the experiments. The validation of several key models of SIMMER-III was also discussed for treating transient behaviors of the solid-particle phase in multiphase flows.

“…This was determined using the method proposed by Saunder [25] in which surfactant was added until the surface tension dropped to the level characteristic of surface saturation. The results are shown in Figure 7, which indicates that 20 mg g -1 of L44 was sufficient to achieve a constant value for the surface tension.…”

The effect of three different molecular weights of a triblock copolymer nonionic surfactant composed of poly(ethylene oxide) and poly(propylene oxide) have been investigated on the zeta potential, stability and rheology of a commercial nanosuspension of 3 mol% yttria stabilised zirconia (3YSZ). Whilst the surfactants showed some evidence of being adsorbed onto the nanoparticle surfaces, it was in insufficient quantities to achieve complete coverage and measurement of the total organic carbon content suggested that the bulk of the surfactants remained in the liquid medium. As a result, there was only a small effect on the zeta potential. Nevertheless, the stability of the suspension was not affected up to solids contents as high as 54 wt%. Whilst the viscosity of the nanosuspension increased slightly with increasing surfactant concentration due to the presence of the polymer molecules, for the lowest molecular weight surfactant the effect was relatively small. Finally, it was observed that if the ionic strength of the suspension was reduced via the removal of free electrolytes in the suspension by dialysis, the viscosity decreased significantly. The reverse behaviour was also observed when extra NH 4 Cl electrolyte was added to the nanosuspension.
