The Navier-Stokes equation for a viscous fluid can be reduced to the difference equation u(t + T) = u0 – Re, if we assume that there is some characteristic flow with period T. In this equation, u is the flow velocity, u0 is some characteristic the speed of the flow, for example, the speed of a body moving in it, and Re is the Reynolds number. What will be the speed of such a periodic flow? Find the condition for the stability of a periodic flow and show that at the stability boundary a d
