Enhancing CO₂ Transport Across a PEEK‐Ionene Membrane and Water‐Lean Solvent Interface

A note on the transport across a diffusive interface

-The ratio of the fluxes of heat and salt across a diffusive interface is investigated on the premise that there are two contributions to the flux of each component. These contributions arise from the two transport mechanisms which can operate at a diffusive interface, viz. double-diffusive convection and turbulent entrainment. Estimates of the fluxes are provided for each process, and their co...

Sugar transport across the hepatocyte plasma membrane.

Physiologically D-glucose transport across the hepatocyte plasma membrane differs from that in most other cells. Most cells in the body extract glucose from the blood as a source of energy or carbon. The liver on the other hand responds to its environment and acts as a 'glucostat'. As the level of glucose in the blood rises, i.e. during feeding, the liver must take it up and store it as glycoge...

Unsteady nanoscale thermal transport across a solid-fluid interface

Energy constrained transport maximization across a fluid interface.

With enhancing mixing in micro- or nanofluidic applications in mind, the problem of maximizing fluid transport across a fluid interface subject to an available energy budget is examined. The optimum cross-interface perturbing velocity is obtained explicitly in the time-periodic instance using an Euler-Lagrange constrained optimization approach. Numerical investigations which calculate transferr...

Solute transport across a contact interface in deformable porous media.

A finite element formulation of neutral solute transport across a contact interface between deformable porous media is implemented and validated against analytical solutions. By reducing the integral statements of external virtual work on the two contacting surfaces into a single contact integral, the algorithm automatically enforces continuity of solute molar flux across the contact interface,...
