English abstract | In this paper we consider the Cauchy problem for the unforced Euler and Navier–Stokes equations for incompressible flows. We give an example of a smooth initial velocity field of finite energy which is self–accelerating, i.e., the maxi- mal speed increases for some time. The self–acceleration is due to the non–Bernoulli part of the pressure generated by the velocity field |
