Finite Volume Scheme for Double Convection-Diffusion Exchange of Solutes in Bicarbonate High-Flux Hollow-Fiber Dialyzer Therapy
Figure 5
Bicarbonate and carbon dioxide diffusive fluxes in the membrane at dialyzer axial distance cm. Diffusive solute fluxes increased as the radial distance increased. Also, diffusion for both solutes was stronger near the fiber walls than the center. The carbon dioxide and bicarbonate ions effect observed before solute stability could enhance the diffusion process during dialysis session.
