volume fraction

The ratio of the volume of a constituent to the volume of the whole. In practice, it may be difficult to determine the volume fraction because differences in the molecular sizes of the constituents may produce a total volume that differs from the sum of the individual volumes of the mixture. When materials of similar physicochemical characteristics (such as multiple aqueous solutions) are combined, this is not a problem.

The effects of solid nanoparticles volume fraction and nanoparticles type on the heat transfer characteristics are investigated and compared with previously published numerical results.
At higher volume fractions of the overall composite, it is evident that Young's modulus falls below results obtained from the ROM.
As the volume fraction increases from 0.25 to 1.00%, compressive strength increases with respect to the GPCC mix without steel fibres.
For the first volume fraction, AE is recorded in the beginning then weak AE is detected (may be the background noise).
Then, bamboo's properties depend on its components such as the volume fraction and distribution of fibers and the interface properties of bamboo components (Shao et al.
The heat transfer characteristics of Gold/DIW nanofluid were investigated by taking into consideration of different factors such as effect of axial distance volume fraction and fluid velocity and Reynolds number.
Since the fibres were preferentially aligned in flow direction for these injection moulded specimens (see SEMs), in broader view the fibre orientation can be assumed roughly unchanged with the fibre volume fraction. When the relative wollastonite fibre volume fraction increased, there is a slight variation in the mean glass and wollastonite fibre lengths.
As the concentration changes during operation, assuming NPs do not precipitate, the new volume fraction of NPs can be found from Eq.
In all, 39 mixes, 13 each for volume fraction of 0.5%, 1.0%, and 1.5% containing different combinations of steel fibres, were tested for compressive strength, split tensile strength, and water permeability at 7,28, 90, and 120 days of curing.
In the present work, [V.sub.CN] and [V.sub.m] are considered as the CNT and matrix volume fraction, respectively.
For this reason, we decided to analyze the nasal structure of two different birds (migratory and non-migratory birds) using volume fraction approach of stereology that gives quantitative data independent of the body sizes of the examined subjects.
