Résumé

L'étude porte sur la théorie de lécoulement non permanent d'un fluide visqueux incompressible dans de canaux rectangulaires d'allongement divers, sous l'influence d'un gradient de pression arbitraire, dépendant du temps. Des solutions ont été obtenues dans 4 cas particuliers: 1. gradient de pression impulsif, 2. gradient de pression constant et établi brusquement, 3. gradient de pression en fonction harmonique du temps, 4. gradient de pression à une composante constante et une composante harmonique. On donne les répartitions de vitesse, les coefficients de frottement et la dissipation d'énergie par unité de longueur.
