Development length in planar channel flows of inelastic non-Newtonian fluids

Development length in planar channel flows of inelastic non-Newtonian fluids

This work presents a numerical study on the development length (L=L/H) required to reach fully-developed flow conditions at the entrance of a planar channel for inelastic non-Newtonian fluids modeled by the Sisko model. The simulations were carried out for low Reynolds number flows in the range 0
