Two-phase Numerical Experiments and Setup

In this study, two numerical experiments are designed for investigating liquid water transport and two-phase dynamics through the 

Fixed pressure boundary conditions, which are equivalent to fixed densities within the LB framework, are imposed at the first layer of the NWP reservoir and the last layer of the WP reservoir. 

Fixed pressure boundary conditions are implemented by assigning the equilibrium distribution functions, computed with zero velocity and specified density at the reservoirs, to the distribution functions. Periodic boundary conditions are applied in the span-wise directions. A particle distribution function bounce-back scheme57 is used at the walls to obtain no-slip boundary condition.
