) equations.
The level-set method is required to capture the interface of the droplet.
For this demonstration, the diffusion coefficient is set to

species X is set to 0 at the inlet. At the outlet, it is set to zero gradient with the assumption of pure
convective transport of species X. Zero-flux condition is enforced at both the upper and the lower walls
of the microchannel.
