Reversibility and Multiplicity in Liquid-Vapor Phase Change
Luiz Eduardo Czelusniak, Alexander J. Wagner, Luben Cabezas Gómez
Using diffuse-interface theory, we uncover unexpected phase-change phenomena that are absent from widely used models of evaporation and condensation. In the inviscid limit, the sam…
Analytical solution for dynamic evaporation of liquid in isothermal condition
Luiz Eduardo Czelusniak, Tim Niklas Bingert, Stephan Simonis +2
An analytical solution based on a diffuse interface model is presented for an isothermal evaporation problem under sub-saturation pressure. The macroscopic equations are derived fr…
On the consistency of pseudo-potential lattice Boltzmann methods
Luiz Eduardo Czelusniak, Tim Niklas Bingert, Mathias J. Krause +1
We derive the partial differential equation (PDE) to which the pseudo-potential lattice Boltzmann method (P-LBM) converges under diffusive scaling, providing a rigorous basis for i…
Effects of gravity induced pressure variations for thermal liquid-gas phase-change simulations with the pseudopotential lattice Boltzmann method
Luiz Eduardo Czelusniak, Luben Cabezas Gómez, Alexander J. Wagner
Direct simulations of phase-change and phase-ordering phenomena are becoming more common. Recently qualitative simulations of boiling phenomena have been undertaken by a large numb…
Shaping the equation of state to improve numerical accuracy and stability of the pseudopotential lattice Boltzmann method
Luiz Eduardo Czelusniak, Vinícius Pessoa Mapelli, Luben Cabezas-Gómez +1
Recently it was discovered that altering the shape of the meta stable and unstable branches of an equation of state (EOS) can greatly improve the numerical accuracy of liquid and g…
Force approach for the pseudopotential lattice Boltzmann method
L. E. Czelusniak, V. P. Mapelli, M. S. Guzella +2
The pseudopotential method is one of the most popular extensions of the lattice Boltzmann method (LBM) for phase change and multiphase flow simulation. One attractive feature of th…
