Abstract

The influence of the non-stationary Basset-Boussinesq forces on the reflection of a step-type pressure wave from a solid surface coated with a porous layer, a saturated liquid or a gas is investigated. The study of wave processes is carried out within the framework of the multi-velocity continuum model. A comparative analysis of the properties of porous screens saturated with a liquid or gas is carried out. The degree of influence of the non-stationary Basset-Boussinesq force on reflection of a wave from a solid wall covered with a porous substance is established.
