Nous étudions un rideau visqueux en écoulement vertical. Un injecteur situé en haut du domaine forme un écoulement ouvert composé d'un liquide visqueux homogène qui s'écoule dans un bain et est accéléré dans son mouvement vertical par l'effet de la gravité. Des zones présentant des taux de contrainte compressifs peuvent apparaître au sein de l'écoulement. Le rideau visqueux est alors susceptible de flamber, perdant sa géométrie plane. Le flambage d'une structure fine et visqueuse a précédemment été étudié dans le contexte d'un écoulement de base présentant une direction d'invariance, ici l'état précontraint est purement bidimensionnel. La modélisation théorique de l'écoulement ouvert prend en compte les effets advectifs. Nous introduirons d...
