Fully-developed pipe and planar flows of multimode viscoelastic fluids
In this page you can download zipped files which contain codes to calculate the velocity and stress profiles for the fully-developed pipe flow solution of multimode PTT fluids (in the exponential and linear versions) with a Newtonian solvent contribution. The problem is solved and explained in the following paper:DOA Cruz, FT Pinho 2006 "Fully-developed pipe and planar flows of multimode viscoelastic fluids" J. Non-Newt. Fluid Mech. 141 (2007) 85-98
