Polymeric Fluid Flow Obeying ECTN Model in an Inclined Circular Tube with Permeable Wall
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 11
Abstract
In this paper, the flow of a polymeric fluid obeying ECTN (Energetically Cross linked Transient Network)model in an inclined circular tube with permeable wall is analyzed. In this study, the rates of segment creation and loss formed by physical and energetic interactions are assumed to be constants. The expressions for the velocity field and the flow rate are obtained. The results are evaluated numerically for various values of physical parameters Nm and . It is found that the flow shows down axially as against Newtonian flow in a circular tube. The flow analysis presented for polymeric fluids has applications in understanding the characteristics of semi-dilute and concentrated solutions of hydrophilic polymers.
