Molecular dynamics simulation of bubble nucleation in hydrophilic nanochannels by surface heating

Bubble nucleation in liquid confined nanochannel is studied using molecular dynamics simulations and compared against the over smooth surfaces (i.e. without confinement). Nucleation argon achieved by heating part of a platinum surface to high temperatures surface-to-liquid algorithm implemented LAMMPS. The hydrophilicity nanochannels increased understand its effect on behaviour. Liquid structuring found play significant role altering thermodynamic properties density pressure nanochannels, which turn changes enthalpy vaporisation. Increased results delay bubble formation as more energy required for nucleation. Thus, delayed hydrophilic can dissipate higher heat fluxes potentially be used thermal management hot spots power electronics.
