© 2021, The Author(s), under exclusive licence to Springer Nature B.V.The experimental study of cooperative fast transport of non-wetting fluid in a disordered nanoporous medium is carried out in this work. New experimental data for simultaneous measurement of fluid flow, filled pore volume and pressure have been obtained. Dependencies of critical pressure and flow on porous particle mass and rapid compression energy have also been established. A new transport mechanism is proposed. The dynamics of fluid transport is represented as a process of evolution of two macroscopic growing modes of transport—spontaneous transport that occurs when new critical pressure of dynamic percolation transition and fluid transport caused by a constant critical pressure under impact compression of nanoporous particles suspension. Following the theory of critical dynamics of multiscale phenomena, a condition for the interaction of modes is proposed. Taking into account this interaction, rapid spontaneous transport is adjusted to the slow impact of impact compression, and the experimental dependencies should be described by the slow mode—impact compression. Such transport occurs simultaneously in two different time scales and is determined by the properties of spontaneous transport. The experimental dependencies are quantitatively described in the kinetic model. Under conditions of filled pores, the response of a fluid transport to impact is characterized by positive feedback.
