✦ Synopsis

A method IS introduced to charactenze a porous structure by a &stnbuted parameter model along with Turner's dead-end pore model

The analysis of expenmental data IS camed out m the frequency domam A transfer function IS obtamed from a set of ptial differential equations which descnbe a system of fluid flow through porous medium

The expenmental data were taken by applying a sinusoidal pressure on the one side of a porous medium, and measunng response pressure wave on the other side of a porous sohd Pulse testing techmque was also employed, and the data were compared with that of the direct smusoldal forcing method Although fiurly good agreement between expenmental and calculated frequency response data were obtamed, the frequency range was hnutted by the sensitivity of the measunng device and mechanical hnutatlon of signal generator The fraction of dead-end pores was calculated from measured frequency response data A transfer function was denved for a gas separation cell which separates gas mixtures through porous bamer to study the separation dynanucs A method IS also suggested which deduces a pore size dlstnbutlon, by solvmg a matnx equation denved from a transfer function of dlstnbuted parameter model
