Unidirectional Transport in Cylindrical Coordinates for Pipe Flow
The core principle involves deriving and solving unsteady momentum balance equations in cylindrical coordinates for laminar pipe flow under oscillatory pressure gradients. This theory utilizes regular perturbation expansions to decouple the governing differential equation into hierarchical orders based on a small parameter, specifically the Womersley number ($Re_\omega$). The approach systematically isolates leading-order viscous solutions (Stokes' Second Problem) and higher-order inertial corrections within fluid dynamics domains governed by Navier-Stokes equations.
