Molecular Simulation of Pulse Heating in Nano-Heater Array and the Effect on Meniscus Evaporation Available to Purchase

Evaporation of a nanoscale meniscus on a nano-heater array surface via pulsed heating is simulated using molecular dynamics. The nano-heaters, each of width 2.56 nm, are evenly spaced on the 28.22 nm wide surface. The temperature of the nano-heaters is increased for a short time period in regular intervals to mimic pulse heating. The simulation results show that the non-evaporating film breaks during the early stages of evaporation due to the pulse heating (unlike a previous simulation performed in absence of pulse heating where non-evaporating film forms). Thus, heat transfer rates can be significantly increased during bubble nucleation and growth by using nano-heater arrays with pulsed heating as it breaks the formation of non-evaporating film allowing the surrounding cooler liquid to come in contact with the surface enhancing heat transfer.
