Résumé

Churilov and Shukhman /1/ have investigated the nonlinear development of Kelvin Helmholtz instabilities in a weakly supercritical stratified shear flow when the interaction is viscous. In that case, the role of the Prandtl number is predominant. This last result is investigated again through nonlinear numerical simulations in which the dissipations are represented by Newtonian cooling and Rayleigh friction.
