Developing Laminar Power‐Law Fluid Flow in Flat Duct

Publication: Journal of Engineering Mechanics
Volume 110, Issue 5

Abstract

An improved version of momentum‐energy‐integral solution for the developing laminar flow of Power‐law fluids in a flat duct is presented. Closed form expressions for the boundary layer development and entrance region pressure distribution are obtained. Results are illustrated graphically and compared with other integral solutions. Analysis predicts the continuity of the slope of pressure drop‐distance curve at the beginning of the fully developed state.
