Thermodynamic equilibrium and stability of liquid films and droplets on fibers

The modeling of liquid spreading and penetration into fibrous materials requires a better understanding of the interactions of thin liquid films and small droplets with single fibers. The wetting properties of fibers may differ significantly from those of plane solid surfaces. Convex surfaces of fibers imply a positive Laplace pressure acting on the liquid-gas interface. This effect causes liquid film instability and hinders droplet spreading....
