1. A mesh system with gradient channels, the system comprising:
a multi-layer woven mesh with increasing mesh pore size bonded to a thermally conducting substrate and having a plurality of nano or microstructured features to increase boiling nucleation sites;
multi-layer interconnected microchannels formed within the mesh and between the mesh d the substrate for capillary liquid wicking; and
self-aligned gradient microchannels, each self-aligned gradient microchannel comprising mesh pores of increasing size extending away from the substrate to promote vapor and liquid to escape from the mesh system;
whereby a critical heat flux and a heat transfer coefficient are increased via capillary liquid film boiling enhancement with accelerated vapor escape for delaying surface dry out.
