Thermoacoustic properties of porous media
The thermoacoustic time constant and flow resistance were measured for steel wool, sand, and a parallel plate geometry over a range of frequencies in one atmosphere of air. The results are compared with that of the theoretical parallel plate geometry. Suitability of various packings for thermoacoust...

| Zusammenfassung: | The thermoacoustic time constant and flow resistance were measured for steel wool, sand, and a parallel plate geometry over a range of frequencies in one atmosphere of air. The results are compared with that of the theoretical parallel plate geometry. Suitability of various packings for thermoacoustic applications will be discussed. [Work supported by ONR.] |
