Titre : Hagen–poiseuille flow in semi-elliptic microchannels Type de document : texte imprimé Auteurs : Rajai S. Alassar, Auteur ; Mohammed Abushoshah, Auteur Année de publication : 2013 Article en page(s) : 04 p. Note générale : fluids engineering Langues : Anglais (eng) Mots-clés : friction  channels (hydraulic engineering)  cross section (physics)  shear (mechanics)  stress concentration  equations  poiseuille flow  microchannels Résumé : In this paper, an exact solution of Hagen–Poiseuille flow in microchannels with semi-elliptic cross sections is obtained. The velocity, shear stress distribution, and the friction factor are calculated and compared to known approximate solutions in the literature. The solution is also verified by comparing the limiting case when the axis ratio approaches unity to the exact solution obtained for semicircular channels.
