The phrase "assuming diffusion" is correct and usable in written English.
It can be used in contexts where you are making a hypothesis or condition based on the process of diffusion, often in scientific or analytical discussions.
Example: "Assuming diffusion occurs uniformly, we can predict the concentration gradient over time."
Alternatives: "presuming diffusion" or "if diffusion is assumed".
LES results indicate that the ADF model assuming diffusion flame structures tends to predict faster propagation of the combustion toward less reactive mixture fractions then the THR model.
Assuming diffusion in the rocks to be anomalous, a flux law that is nonlocal in space and time is used to develop a mathematical model for fractured rocks drained by a horizontal well produced through multiple transverse hydraulic fractures.
In this work, analytical solutions were derived (for any methanol oxidation reaction order) for the profiles of methanol concentration and proton current density, by assuming diffusion mass transport mechanism, Tafel kinetics, and fast proton transport in the anodic catalyst layer of a direct methanol fuel cell.
In the present study, the mass transfer has been studied according to the model (Eq. 8) suggested by Mckay et al. assuming diffusion resistance within the particle to be negligible.
This results follows from the concentration dependent threshold effect, just described previously, without assuming diffusion for KNI and for zygotically produced HB.
To understand whether localization of membrane receptors into low-diffusivity microdomains (lipid rafts) on the cell surface is influenced by receptor dimerization, MC simulations were run for different values of the rate constants for receptor dimerization and monomerization, assuming diffusion of particles is reduced in specified regions (lipid rafts) on the lattice.
Assuming diffusion-controlled uptake, significant ammonia loss to flyash is predicted; this is not supported by industrial experience.
Under quasiestatic conditions, assuming diffusion-controlled mechanisms at GB, the model predicts a strain-rate sensitivity increase in nanocrystalline samples with respect to the coarse-grained material of the same order as in recently published experiments.
The mathematical relationship between porosity of the structure and maximum current density was determined based on an assumed diffusion coefficient value with fixed porosity through the body and varying tortuosity through the thickness of the diffusion media.
The inferred peak position has a modest dependence on the assumed diffusion coefficient of Ca2+ (DCa), which was modeled over the range of 100 to 300 µm2 s−1 (Fig. 6).
Although the above model assumes diffusion within a corral, both processes probably influence synaptic AMPAR diffusion in vivo.
