  Effect of high and low Reynolds number is studied on low frequency
vibrational modes of a spherical virus embedded in the aqueous medium. We have
used an analytical approach based on fluid dynamic and classical Lamb theory to
calculate the vibrational modes of a virus with material parameters of lysozyme
crystal in water. The obvious size effect on the vibrational modes is observed.
The estimated damping time which is of the order of picosecond varies with
Reynolds number and shows a high value for a critical Reynolds number. The
stationary eigenfrequency regions are observed for every quantum number l and n
suggesting the most probable Re ranges for acoustic treatment of viruses in
order to detect or annihilate the virus using corresponding viruswater
configuration.
