Integrating Nanoscale Dynamics for Enhanced Evaporation: A Theoretical Framework Addressing Nonlocal Transport in Nanopores

Evaporation from nanopores is of great interest in nature and many industrial applications. Therefore, understanding the transport processes within a pore requires integrating the dynamics of vapor and liquid flow, and interfacial interactions are essential. The vapor movement is classified as free molecular flow due to the modest size of the pore (about 100 nm) compared to the mean free path (roughly
$1.1\ \mu m$
). Our research will begin by determining the possibility of liquid molecules evaporating from the surface and entering the pore and the probability of vapor molecules condensing back onto the surface once they reach the pore's end. We then investigate the effects of various operating factors to identify settings that optimize nanopore evaporation.
