Abstract
Measured data on the filtration velocity of air in highly porous cellular materials under conditions of high filtration velocities and reduced air densities are reported. The viscosity and inertia coefficients entering the quadratic dependence of pressure gradient as a function of filtration velocity in porous materials for various flow conditions in the pores are evaluated.
