Kelvin–Helmholtz Instability
Interfacial growth of horizontally stratified two immiscible fluids with a small density difference is simulated using the lattice Boltzmann method (LBM) for two-phase flows. In the Kelvin–Helmholtz instability, time variations of the interface are numerically investigated in several cases. After a velocity difference is initially applied to the fluids at rest, the interface either grows or decays according to the non-dimensional parameter related to the gravitational force and the surface tension. As the magnitude of the velocity difference is increased, the interface becomes unstable and finally leads to a peculiar shape, which is generally called “a cat’s eye” in fluid dynamics.
