A Numerical Model for Two-Dimensional Oscillatory Flow and Oxygen Transfer in the Axial Plasmatic Gaps of Capillaries

Abstract

Time varying flows of plasma in the axial gaps between erythrocytes in a mathematical model of a capillary have been solved from the complete Navier-Stokes equations by a finite-difference method. The erythrocytes are considered to be disk-like and to span the entire lumen. Secondary flow patterns, pressure and shear distributions between the erythrocytes are obtained as a function of time, and the pressure drop is compared with previous results for steady creeping flow. The rate of oxygen transfer from the cells is calculated from a numerical solution of the convective diffusion equation.
