“…Although this issue of dual-scale flow behavior has existed for some time and there have been subsequent models that have addressed this issue [2,6,[27][28][29][30][31][32][33][34], only recently have simulations developed capabilities to account for fiber tow saturation separately, in addition to predicting the movement of the macroscopic flow front [17,35,36]. However, such simulations require one to provide a fiber tow permeability value in addition the bulk permeability value for the preform under consideration.…”
