L'objectif de cette thèse porte sur l'étude des phénomènes de blocage dans un flux particules à faible densité dans un canal. Le blocage est induit par la géométrie du canal. L'essentiel de mes travaux concerne la description des situations où le blocage est contrôlé par les limites en capacité d'un canal. Le paramètre pertinent pour ce phénomène est donné par le nombre de particules minimum, N, conduisant à l'interruption du flux de particules. Un modèle stochastique simple introduit par Gabrielli et al. (PRL. 110, 170601, 2013) illustre ce comportement: des particules arrivent aléatoirement selon une distribution de Poisson à l'entrée d'un canal unidimensionnel et le traversent avec un temps constant, noté t. Le blocage survient lorsque N...
