Obstacles perturb laminar gas flow by creating turbulences interspersed with isolated eddies of finite lifetime. Their decay causes a cascade of smaller eddies ending, finally, as victims of molecular friction. A good deal of the turbulence energy carried by the eddies is lost in the form of acoustic waves. Two classes of electric current compatible with the quasi-hydrodynamic plasma model are presented. The corresponding eddy structures are insular, finite and absolutely rotating.
