Sentence examples for mass diffusion for from inspiring English sources
It is thus most suitable for modeling small values of physical mass diffusion, for which adequate numerical resolution is computationally demanding.
Appreciable upstream mass diffusion from the nozzle exit for Sc < 0.5 explains the flame behaviour for hydrogen fuel such that a nozzle-attached flame exists even up to jet velocities comparable to the speed of sound.
Sensitivity analyses suggest that inaccuracies in three-body termination rates for H + O2 + M = HO2 + M reactions and in mass diffusion coefficients for H2 diffusion are the most likely explanation for the near-limit differences.
Time scales based on heat transfer (convective heat transfer and thermal diffusion) and mass diffusion accounting for the internal motion were estimated.
The relation between experimental catalyst sintering data and the effective mass diffusion constant for Ni-OH is established by numerical modelling of the particle migration and coalescence process.
A fixed mesh was used, with spacing varied to accomodate the deep thermal diffusion during the long time needed for mass diffusion.
For mass diffusion in Laminar flows: In the above Eq. (8), which arises due to concentration gradients; in the present model, dilute approximation was assumed, which is defined as follows: overrightarrow {{J_{i} }} = - rho D_{i,m} nabla Y_{i} (9).
The holes in the shell became a shortcut for mass diffusion and transference.
Second, a depletion layer of reactants in the interfacial region is formed with the progression of reaction, and center-of-mass diffusion of reactants is required for further reaction which results in a transition of the power law relationship into [Area] ∼ t1/2.
LN significantly contributed to the development of knowledge in the field of composite materials, rheology, energy and mass diffusion through polymers, and materials for biomedical application.
The model accounts for internal mass diffusion resistance, surface mass transfer resistance, external film heat transfer resistance, and heat transfer to the surrounding environment.
