Validation of multicomponent lattice Boltzmann equation simulations using theoretical calculations of immiscible drop shape.

Quantitative comparison between the measured deformation of a neutrally buoyant drop, obtained with an appropriately conceived three-dimensional, multicomponent lattice Boltzmann equation simulation methods for continuum multicomponent hydrodynamics [Phys. Rev. E 76, 026708 (2007); 76, 026709 (2007)], are shown to be in agreement with the theoretical predictions of Taylor and Acrivos [J. Fluid. Mech. 18(3), 466 (1964)].
