Description
The effect of viscosity on the destabilization of the Rayleigh-Taylor (RT) instability by thermal conductivity has been investigated as an extension of the Ryutov analysis [D. D. Ryutov, Phys. Plasmas 7, 4797 (2000)]. The viscosity stabilizes the RT instability for short wavelength perturbations when gradients of a molecular weight and a gravitational acceleration are in the same direction. It only reduces the growth rate for short wavelength perturbations when they are in the opposite directions. The growth rates have been quantitatively evaluated as functions of a normalized wavelength for various Prandtl numbers in the case when adiabatic perturbations are neutrally stable
