WebOct 1, 1999 · The effect of viscosity on the wave resistance experienced by a two-dimensional perturbation moving at uniform velocity over the free surface of a fluid is investigated. The analysis is based on Rayleigh's linearized theory of capillary-gravity waves. It is shown in particular that the wave resistance remains bounded as the … Webgravity waves subjected only to molecular viscosity [Vadas and Fritts, 2004]. That work described only part of the thermospheric damping, however, because the Prandtl num-ber throughout the mesosphere and lower thermosphere is approximately 0.7 [Kundu, 1990], suggesting similar damp-ing rates from kinematic viscosity and thermal diffusivity.
