Numerical investigation of multiple droplet growth dynamics on a solid surface using three-dimensional lattice Boltzmann simulations

We present an investigation of multiple droplet growth dynamics on homogeneous and patterned surfaces during dropwise condensation. Our analysis is based three-dimensional thermal lattice Boltzmann simulations. First, we investigate the surfaces. The droplets a surface shows that lower static contact angle surface, higher condensed volume liquid. After that, discuss (a with hydrophilic hydrophobic regions). show pattern formed by completely different from surface. This due to pinning effect at interface hydrophilic–hydrophobic region. Moreover, shape not spherical, as observe in case also demonstrate V for all than However, decreases increase then size spot. find increases radius
