Apparatus to determine the complex mass of a viscous fluid contained in a rigid porous solid from acoustic pressure measurements.

Two experimental techniques to determine the frequency-dependent complex mass of a viscous fluid contained in a rigid porous solid are investigated. In one technique the moving mass of the fluid is by its effect on the measured input electrical impedance of a moving coil transducer. In the second te...

In one technique the moving mass of the fluid is by its effect on the measured input electrical impedance of a moving coil transducer. In the second technique the moving mass is extracted from the measured acoustic pressure required for the fluid to oscillate with a known amplitude through the solid frame. A description of the apparatus and preliminary results using the pressure method as well as a comparison of the two techniques are presented.
