On detection and annihilation of spherical virus embedded in a fluid matrix at low and moderate Reynolds number

Abstract

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.
