Resumen
In the last decade, mucc effort has been devoted to the understanding of near Wall turbulence, both through experimental and numerical observations.Different scenarios have been proposed, but a broad consensus on a basic model for the near Wall events has still not been achieved. We present here a simple numerical model for some of the events occurring during the bursting phenomenon.In particular we study the behaviour of longitudinal vórtices as they are brought near a wall by an x-dependent external shear, wich is the near Wall equivalent of a plane strain. We also study the effect or the interaction on the local Wall stress, and we calculate the distribution of turbulent stresses to analyse the zones of máximum production in the transversal y-z plane.
