Abstract

A method is described for measuring the Reynolds number dependent permeability in order to consider the inertial effects of the flow through porous media. A nonlinear correction term is introduced and the corresponding coefficients are determined by inverse analysis. The method is based on an optimization process between computed and measured pressures at various locations in the mold and flow rates at the gate during steady state gas flow through the enclosed fiber preform. The computed pressure is obtained by the control volume finite element method (CVFEM). The proposed method was demonstrated by using a specially designed mold with multiple ports for gas injection and pressure measurement and it was shown that it could be implemented easily while yielding consistent and reliable results.
