Numerical Simulation of Kelvin-Helmholtz Instability using Volume-Of-Fluid Method abstract
In this article, the Kelvin-Helmholtz instabilities, which are produced by shear at the interface between two fluids with different physical properties, are simulated and studied. In order to obtain the Kelvin-Helmholtz instability, the inlet velocity is defined as a sinusoidal perturbation. By taking the gravity and surface tension into account, we demonstrated the development of the instability for the critical value of the wave number. It is shown that the VOF method along with the SGIP model is an appropriate method for simulating Kelvin-Helmholtz instability.
