Influence of diffusion and sorption on sound propagation in multiscale porous materials (2017)
Presentation / Conference
Venegas, R., Boutin, C., & Umnova, O. (2017, July). Influence of diffusion and sorption on sound propagation in multiscale porous materials. Presented at 6th Biot Conference on Poromechanics, Paris, France

This paper investigates sound propagation in multiscale sorptive porous materials saturated with a pure gas. An example of this type of materials is a packing of porous grains where a mesoscopic, microscopic, and nanoscopic scale can be identified. T...

Low frequency sound absorption in a porous material with periodically distributed dead-end pores
Presentation / Conference
Leclaire, P., Umnova, O., Dupont, T., & Panneton, R. Low frequency sound absorption in a porous material with periodically distributed dead-end pores. Presented at EuroNoise 2015, Maastricht, Netherlands

A theoretical and numerical study of the sound propagation in air-saturated porous media with straight pores bearing lateral cavities (dead-ends) is proposed. The straight pores can be considered as the main (Biot) pores. The lateral cavities are loc...
