The erosion of pipe bends in pneumatic conveying systems
… involved in the erosive wear process in 90 pipe bends, by a stream of pneumatically conveyed suspensions of solid particles. From appropriate analysis of the test data, a basis of correlation in terms of the respective parameters has been established, from which the likelihood of erosion …

Mathematical and computational modelling for the design of pipe bends and compliant systems
… when modelling the flow of a fluid through a pipe bend or deflector nozzle. These numerical processes include a new form of numerical integration and a finite element formulation which, it is suggested, could readily be extended to handle further realistic problems based on the pseudo three …

Computational fluid dynamics (CFD) modelling of critical velocity for sand transport flow regimes in multiphase pipe bends.
… of hydrocarbon fluids in multiphase pipelines could be severely hindered by particulate solids deposit - such as the sand particles that can accompany hydrocarbon production. Knowledge of the flow characteristics of solid particles in fluids when transported in pipelines is important, …

Design of soft-body robot with wireless communication for leak detection in large diameter pipe systems
… or low cost methods to detect leaks, a soft-body pipe leak detection robot has been developed to traverse small, 50mm diameter water pipe systems. This robot has proven to be effective in small diameter pipes, but its scalability for large diameter pipes is unknown. The focus of this thesis is to …

Structural integrity assessment of engineering components under cyclic loading at high temperature
… cyclic plasticity behaviours of 90° back-to-back pipe bends under cyclic thermo-mechanical load and constant pressure. Another numerical study investigates creep-cyclic plasticity behaviours of Particle Reinforced Titanium Matrix Composites (PRTMCs), which is a futuristic engineering material, …

CFD modelling of flow-induced vibration under multiphase flow regimes.
… multiphase flow-induced vibration (MFIV) in pipe bends poses serious problems in oil and gas, nuclear and chemical flow systems. The problems include: high amplitude displacement of the pipe structure due to resonance; fatigue failure due to excessive cyclic stress, induced by fluctuating …

Interplay of Water Chemistry and Entrained Particulates in Erosion Corrosion of Copper and Nonleaded Alloys in Potable Water Systems
… evidence. Large-scale recirculating hot water pipe-loop experiments demonstrated that an aggressive hard water with entrained aragonite (CaCO3) particles could cause fully penetrative failures (i.e., leaks) in brand new copper pipe and nonleaded brass fittings in just 3-49 days. This represents …

CFD modelling of pipe erosion under multiphase flow regimes.
Pipe erosion due to sand transport can have an adverse effect on the production efficiency of pipe-lines and other related flow systems. Proper knowledge of the flow characteristics, particle behaviour and geometric effects is very important in the accurate prediction of erosion rates and location. …
