Viscosity is only suppressing roll-up motion by reducing relative velocity. Richardson number to trigger Kelvin-Helmholtz Instability. Two de-composed parts of Richardson Number. The body force of Richardson number is dominant for generation/strength of KHI. Surface tension affect to KHI as same as viscosity.
