Sentence examples for mass diffusion times from inspiring English sources
While in the limit of vanishingly small local heat and mass diffusion times, they reduce to the classical ideal pseudo-homogeneous reactor models, they are also capable of capturing the mixing or mass (and/or heat) transfer-limited asymptotes for the case of fast reactions.
Heat and mass diffusion time are calculated from the scaling analysis of the governing equations.
It was shown that the unsteady heating duration of the droplet fall within the two limits set by the heat transfer and mass diffusion time scales.
Analysis of results indicates that the adsorption process is controlled by heat diffusion resistance when heat diffusion time to mass diffusion time ratio (tth/tm)~O(100) or more.
However, it is found that the lower temperature of the HVOF jet compared to plasma results in slower vaporization and solute mass diffusion time inside the droplet, leading to comparatively thicker shells.
When the corresponding variation of the solvent content is of the same order than the variation due to the sorption experiment and when the thermal time constant is significant compared to the characteristic mass diffusion time, this thermal effect must be taken into account when analyzing sorption data.
Thus it follows that species concentration increases with an increase in time or mass diffusion rate.
The governing equation of a micro-beam deflection is obtained using Hamilton's principle and also the governing equations of thermo-diffusive elastic damping are established by using two dimensional non-Fourier heat conduction and non-Fickian mass diffusion models with one relaxation time based on continuum theory frame.
A novel technique for short-time measurement of mass diffusion coefficients in transparent liquids using counter flow type diffusion cell has been proposed.
A fixed mesh was used, with spacing varied to accomodate the deep thermal diffusion during the long time needed for mass diffusion.
At the same time, since the mass diffusion of reactant adatoms on the side surface, continuous growth resulting in the formation of tapered teeth (stage IV in Fig. 4).
