Slug genesis in cylindrical pipe flow
Transition to uniform turbulence in cylindrical pipe flow occurs experimentally via the spatial expansion of isolated coherent structures called ‘slugs’, triggered by localised finite-amplitude disturbances. We study this process numerically by examining the preferred route in phase space through which a critical disturbance initiates a ‘slug’. This entails first identifying the relative attrac...
متن کاملNumerical Investigation of Vortex Interaction in Pipe Flow
To discover the nonlinear characteristics of pipe flow, we simulated the flow as a sum of many vortex rings. As a first step, we investigated the nonlinear interaction among a maximum of three vortex rings. The pipe wall was replaced by many bound vortices. A free vortex ring moves right or left according to the radius, and that of a particular radius keeps the initial position. The energy of a...
متن کاملNumerical Studies of Unsteady Friction in Transient Pipe Flow
In this thesis, unsteady friction in transient pipe flow is given a closer look. The common quasi-steady friction model and two one-dimensional convolution-based models, developed by Zarzycki and Vardy & Brown, are considered. A quasi-two-dimensional approach to the water hammer problem is also derived, where the pipe friction is related to the near-wall behavior of the velocity profile. The mo...
متن کاملNumerical Investigation of Temperature Distribution in an Eroded Bend Pipe and Prediction of Erosion Reduced Thickness
Accurate prediction of erosion thickness is essential for pipe engineering. The objective of the present paper is to study the temperature distribution in an eroded bend pipe and find a new method to predict the erosion reduced thickness. Computational fluid dynamic (CFD) simulations with FLUENT software are carried out to investigate the temperature field. And effects of oil inlet rate, oil in...
متن کاملTechniques of analysis for nonlinear transient flow in a pipe
Analytical solutions to the time-dependent, nonlinear equation governing incompressible, one dimensional flow in a pipe are presented. The flow is pressure-driven, and a valve on the pipe controls the flow rate. Power-law losses and an exponential closing action of a valve are assumed. Four different approximation methods are used. Of these, perturbation and Adomian’s decomposition are seen to ...
