Figure 1.

A schematic view of the studied configuration: (a) shows the case of a linear shear flow obtained by imposing the velocity of the upper and lower walls; (b) shows a similar configuration but for a Poiseuille flow; the imposed flow is generated by a bulk force term f_bulk, which ensures a parabolic profile with maximal velocity u_max. In both configurations, the ATP concentration a is defined on Ω_ex, and a Neumann boundary condition is imposed on the moving boundary X(s). To view this figure in color, go online.
