Variation in dynamic viscosity ([eta]) with temperature and (inset) variation in complex viscosity ([eta]*) with temperature in the PC-GF composites.
where [K.sub.[eta]] = 3,7 x [10.sup.-9] Pas is viscosity coefficient, [eta] = 17,3 x [10.sup.-6] Pas is dynamic viscosity of air during normal conditions, [d.sub.[??]m] = 140 [micro]m is arithmetic mean diameter of fly ash particles and dispersion coefficient is defined by equation
(4) The seepage time increases with the increase in the dynamic viscosity. The greater the dynamic viscosity, the greater the interaction between the particles, the stronger the water-blocking ability, and the longer the seepage time.
The variation laws of density and dynamic viscosity under different water yield properties were analyzed based on the experimental results.
Small values of dynamic viscosity for L4 and L5 are attributed to their synthetic origin and having SAE grade 5W-40.
The Influence of Dynamic Viscosity [mu] on the Shock Behavior.
The dynamic viscosity of nanocomposites made from select isolated fraction of homogeneous single length nanotubes was shown in Figures 8, 9, and 10.
In another study conducted by Animasaun and Aluko [15], it is reported that when dynamic viscosity of air is assumed to vary linearly with temperature, normal negligible effect of Eckert number on velocity profiles will be noticed.
where [??] represents the fluid velocity in each spatial direction, p is the fluid pressure, [rho] and [mu] are the fluid density and the fluid dynamic viscosity, respectively, [[mu].sub.t] represents the turbulent viscosity, and [K.sub.t] is the turbulent kinetic energy.
The density and dynamic viscosity vary smoothly over the interface, and the average density and dynamic viscosity can be defined using the level set function [30, 31]:
