Výpočet hustotních profilů nano-kapiček použitím gradientní teorie: numerické řešení v transformovaných proměnných
 Hrubý, Jan
The Cahn-Hilliard gradient theory extends the continuum fluid mechanics and thermodynamics to objects of typical dimensions of 1 nm. The present investigation concerns the computation of the density profile of a equilibrium spherical case (droplet, bubble). The solution for this case reduces to a single second-order ordinary differential equation (ODE) with boundary conditions. To overcome computational difficulties due to the tremendous difference of thermodynamic properties of the liquid and vapor phases at low temperatures, we suggest some mathematical transforms. Using these transforms, the right-hand side of the ODE becomes well-behaved and the numerical solution is converging.
