We propose a domain decomposition method for advection-diffusion- reaction equations based on Nitsche's transmission conditions. The advection-dominated case is stabilized using a continuous interior penalty approach based on the jumps in the gradient over ...
The effect of drainage front morphology on gaseous diffusion through partially saturated porous media is analyzed using the lattice Boltzmann method (LBM). Flow regimes for immiscible displacement in porous media have been characterized as stable displacem ...
A new, low production cost, technique for the preparation of boron-doped diamond electrodes (BDD) is presented. The technique is based on mechanical implantation of BDD particles into a titanium substrate. The electrochemical characterization of low covera ...
Articular cartilage plays important roles in weight-bearing, lubrication, and load distribution in articulating joints. The tissue is mostly extracellular matrix (>90% by volume) that is synthesized and remodeled by cells (chondrocytes) embedded within. Ad ...
Experimental observations in stationary ECRH discharges in TCV show that additional heating has a strong effect on the electron density profile. In the absence of MHD activity or strong internal transport barriers, additional electron heating generally lea ...
The influence of partial substitution of Fe with Ti on the oxygen transport properties of La1−xSrxFeO3 membranes was investigated in view of their application for oxygen separation. Samples of composition La0.5Sr0.5Fe1−yTiyO3−δ(y=0, 0.2) were prepared and ...
The temporal stability and effective order of two different direct high-order Stokes solvers are examined. Both solvers start from the primitive variables formulation of the Stokes problem, but are distinct by the numerical uncoupling they apply on the Sto ...
Soil evaporation plays an important role in the hydrologic cycle and affects near surface energy balance. Changes in evaporative drying rates reflect complex interplay between soil pore space and transport properties and atmospheric conditions. Typically, ...
The role of the current profile and ion and electron temperature ratio in Tokamak A Configuration Variable (TCV) electron internal transport barrier (eITB) noninductive discharges is inspected by means of the linear gyrokinetic global code LORB5 (Bottino e ...
