Pipe flow stability
Webbstability is associated with the interaction of three-dimensional disturbances and streamwise rolls. INTRODUCTION "Classical" shear flows as pipe Poiseuille flow, plane Couette flow have received much considerations for the recent years. The active interest in the flows is associated with the problem of bypass in laminar-turbulent transition.

WebbWhile hydrodynamic stability and transition to turbulence in straight pipes – being one of the most fundamental problems in fluid mechanics – has been studied extensively, the stability properties and the route to turbulence of the flow inside curved pipes is not yet understood; in fact only very limited literature exists on this flow case. WebbIn this article, we study a periodic boundary value problem related to valveless pumping. The valveless pumping is described by the unidirectional flow of liquid in a system. We establish some conditions for globally asymptotic stability and the existence of a positive periodic solution to the considered equation. Finally, a numerical example shows that the …

The flow fields considered consist of a steady pressure gradient-driven velocity field combined with a purely oscillatory component generated by either an oscillatory pressure gradient or by harmonically oscillating bounding surfaces. Webb4 juni 1998 · Stability of the flow of incompressible viscous fluid in a circular pipe is studied numerically. A perturbation consisting of finite‐amplitude two‐dimensional and infinitesimal three‐dimensional parts is imposed on the basic flow. The temporal evolution of the perturbation is analyzed by direct numerical calculation of the Navier–Stokes …
