Abstract
In this paper, a liquid droplet solidification contacting cold solid surface is modeled by a novel multicomponent multiphase enthalpy-based lattice Boltzmann method (LBM). The freezing process of liquid droplet coupled with thermal and mass transfer on cold flat surface with different wettability (θ = 160°, 135°, 60°, 20°) is investigated in detail. The solid volume fraction of droplet solidification with Fourier number are shown under different contact angles. The simulation results show that the solidification time for droplet contacting on a hydrophilic surface is much smaller than that of hydrophobic surface when liquid droplet shares the same initial radius.
