First, simulation through one cylinder was used to calibrate model by comparing the separation angle of experiments executed by Sucker & Brauer (1975) and the separation angle of simulations. Moreover, streamlines profile were compared for different Reynolds numbers. Intermediate or turbulent flow (Red = 600) imposed the choice of turbulence models. It is proved that the standard model, k-epsilon, is not well adapted to simulate the flow around a curved body. The SST-k-omega model resulted in better simulations. Geometry and boundary conditions were taken as common used (Newman and Dirichlet). Once the model was calibrated, simulations were run with a bundle of capillary fibers (membrane network). Velocity, velocity gradient, and friction coefficient were used to define optimal design according to experimental results. ©2011 Walter de Gruyter GmbH & Co.
