Description
Summary:The intellectual properties of a suspension of a granular nanoporous medium in a non-wetting liquid under conditions of a pulsed pressure change are discussed in the work. The characteristic response time (0.1 ÷ 10) ms and the high specific energy intensity of the impact energy conversion (E) (10 ÷ 100) J / g make attractive the use of the such type suspensions in shock / explosion absorption devices. In the process of rapid compression upon impact and when the critical pressure (P0) is reached, the suspension is transformed into a new state with a change in the compressibility (χ = dV / dP) by (2 ÷ 4) of the order. In the new state, the process of volume reduction does not depend on the temperature and viscosity of the liquid, it is practically non-dissipative and at constant pressure. A microscopic mechanism of such a nontrivial nonlinear response is proposed. The intellectual properties of a suspended granular nanoporous medium in a non-wetting liquid under conditions of pulsed pressure changes are considered using of the Libersorb 23-water system as an example.
