From: Pulsatile flow drivers in brain parenchyma and perivascular spaces: a resistance network model study
Two vessel model baseline results. a Fluid pressure produced by volumetric fluid sources over the course of one period. See Fig. 1 for source labels. b PVS fluid velocity over the course of one period. See Fig. 1 for resistor labels. c Parenchyma fluid velocity for resistors parallel and perpendicular to the vessels over the course of one period. d PVS Peclet numbers for a range of physiologically relevant diffusivities. e Parenchyma Peclet numbers with radial distance from the PVS outer radius for a range of physiologically relevant diffusivities. Peclet numbers were computed with the distance between vessels as the characteristic length (Eq. 12) for all cases except those marked (**) for which pore size was the characteristic length (Eq. 13)
