Enhanced energy conversion as a result of fluid-solid interaction in micro- and nanoscale

It is known that nano- and micromechanics require new approaches to right describing of
surface-like phenomena which lead to an enhanced energy conversion. In this work, a general
form of surface forces that consist of a contribution from both the friction and mobility
components has been extended to collect the effects of bulk and surface motion of a fluid.
Quite similar impact can be observed for a solid-fluid mixture, where the principle of effective
stress for this new type of approach should be considered from the very beginning. The second
motivation of our work is to present the multiscale domain of fluid-solid interaction which
describes some “emergence effects” for materials with especially high volumetric surface
densities.
