TL;DR
This paper studies how temperature and concentration affect the flow of a special fluid through a flexible channel, which could help improve medical devices.
Contribution
The study introduces a model for peristaltic flow of a Carreau fluid with variable viscosity influenced by temperature and concentration.
Findings
Higher temperature increases fluid velocity and reduces flow resistance in the channel.
Increased solute concentration also enhances fluid velocity and lowers resistance.
The model provides insights for optimizing biomedical transport systems under physiological conditions.
Abstract
Peristaltic or undulating flow plays a significant role in various biomedical and industrial processes, where it provides an efficient mechanism for transporting fluids through flexible conduits such as catheters and endoscopic channels. Understanding such flow behavior is essential for improving medical devices and industrial applications involving non-Newtonian fluids. This study investigates the peristaltic motion of a Carreau fluid whose viscosity varies with both temperature and concentration within a flexible, axisymmetric channel composed of two overlapping cylindrical tubes. The outer wall of the channel exhibits a sinusoidal wave pattern, simulating a realistic endoscopic configuration. The governing nonlinear, nonhomogeneous partial differential equations were formulated in cylindrical coordinates under the assumption of a long wavelength and low Reynolds number. The…
