Sentence examples for moving boundary diffusion from inspiring English sources

In the present work, moving boundary diffusion problems have been simulated for two cases.

Mathematically, analysis of drug delivery kinetics involves two moving boundary problems: diffusion front and eroding front.

This paper focuses on the use of a simple one-dimensional model considering moving boundary vapor diffusion to describe the ultrasonic assisted atmospheric freeze-drying of foodstuffs.

The Fickian diffusion with moving boundary model can be extended to evaluate different geometries for controlled release systems.

The model is based on transport by random walk and certain rules at the phase interfaces which mimic the continuous solution of the diffusion and moving boundary problem.

The X-ray contrast of the particles is caused by an inhomogeneous distribution of impurity atoms (Mo, Fe and Al), whose density profile around growing nanoparticles was simulated by solving the corresponding diffusion equation with moving boundary conditions.

The Thiele modulus of the reaction governs the behavior of the moving boundary between the reaction zone and the diffusion zone.

We also treat the case of differing diffusivities for fuel vapor, oxidizer, and sensible heat (nonunity Lewis numbers); that is, we undertake an explicit Stefan problem, in which the diffusion-flame locus is the moving boundary.

We consider the model problem of mass transport by diffusion with chemical reaction at a moving boundary.

Aided by Thermo-calc & DICTRA software package, the concentration profiles of W and V in established diffusion couples were calculated by the moving boundary model according to revised dynamic parameters and MOB database, respectively.

The particles will sediment by forming a moving boundary, which creates a concentration gradient that also induces diffusion flux.
