Simulation of static critical phenomena in non-ideal fluids with the
Lattice Boltzmann method    [PDF]

M. Gross, F. Varnik

A fluctuating non-ideal fluid at its critical point is simulated with the
Lattice Boltzmann method. It is demonstrated that the method, employing a
Ginzburg-Landau free energy functional, correctly reproduces the static
critical behavior associated with the Ising universality class. A finite-size
scaling analysis is applied to determine the critical exponents related to the
order parameter, compressibility and specific heat. A particular focus is put
on finite-size effects and issues related to the global conservation of the
order-parameter.
