On the basis of simple mass partitioning calculations, one can derive estimates of typical DNAPL source zone longevities that span centuries under natural gradient conditions, or even longer time periods if hydraulic isolation is attempted.
The resulting added-mass partitioned (AMP) algorithm is stable even for very light structures, requires no sub-iterations per time step, and is second-order accurate.
An added-mass partitioned (AMP) algorithm is described for solving fluid structure interaction (FSI) problems coupling incompressible flows with thin elastic structures undergoing finite deformations.
Thisresults of the analysis are confirmed with numerical simulations that also demonstrate a second-order accurate impartitionedn of the AMP scheme.
Importantly, these new added-mass partitioned (AMP) schemes are stable and retain full accuracy with no sub-iterations per time step, even in the presence of strong added-mass effects (e.g. for light solids).
We describe an added-mass partitioned (AMP) algorithm for solving fluid structure interaction (FSI) problems involving inviscid compressible fluids interacting with nonlinear solids that undergo large rotations and displacements.
This new added-mass partitioned (AMP) algorithm extends the previous developments in [1], [2] by generalizing the added-damping tensors to account for arbitrary three-dimensional rotations, and by employing a general quadrature for the surface integral over a rigid body to derive the discrete AMP interface condition for the fluid pressure.
The surfoplexes were characterized for extent and site of complexation, stability, mass and partition coefficient.
The influence of the composition of the phase system on mass transfer, partition behaviour and reaction kinetics was identified by independent experiments.
In this work, a parameter estimation approach was used to review and to determine the mass transfer partition and diffusion coefficients governing the migration process of eight antioxidants from poly(lactic acid), PLA, based films into water/ethanol solutions at temperatures between 20 and 50 °C.
