Efficient moment method for modeling nanoporous evaporation

Evaporative nanoporous membranes have the potential to unlock next generation of high-power electronics by providing much needed compact and efficient cooling solutions. Here, we develop a novel modeling framework for this class flows and, in doing so, demonstrate that conventional fluid mechanics, based on Navier-Stokes-Fourier paradigm is inaccurate, because domain sizes are comparable mean free path gas (i.e. vapor flow rarefied). Instead, show recently developed higher-order moment methods provide both an accurate method computing these evaporative thus simulation-for-design capabilities at nanoscale.
