WebThe energy decay of vortices in viscous fluids governed by the compressible Navier-Stokes equations is investigated. It is shown that the main reason for the slow decay is that zero eigenvalues exist in the matrix related to the dissipative terms. The theoretical analysis is purely mathematical and based on the energy method. WebA NOTE ON THE DECAY OF VORTICES IN A VISCOUS FLUID V´IT PR ˚UˇSA AND K. R. RAJAGOPAL Abstract.
