Determination of permeability and tortuosity of permeable media by ultrasonic method. Studies for sintered bronze

Jan Kochański, Mariusz Kaczmarek, Józef Kubik
The paper presents a combined graphical and analytical method of determination of two structural parameters of a permeable medium: permeability and tortuosity. The method is based on a two-phase model of permeable material and uses experimental data from ultrasonic studies of wave parameters in alcohol-saturated sintered bronze.
Keywords: saturated porous materials; ultrasonic waves; attenuation
