Investigating the effects of viscosity and density ratio on the numerical analysis of Rayleigh-Taylor instability in two-phase flow using Lattice Boltzmann method: From early stage to equilibrium state

作者：

Highlights：

• The LBM is used to investigate the complete behavior of RTI numerical model.

• Good agreements with experiment and other numerical studies are obtained.

• Instability rate is found to be greatly affected by Atwood numbers.

• The equilibrium state of the instability is successfully simulated.
