Coupled level set and CFD (computational fluid dynamics) methods are adopted in this work to track the moving gas–liquid interfaces riser of an external loop airlift photobioreactor (ALR) which microalgae used produce biofuels capture CO2 from flue-gas. Modeling behavior gas bubbles is a crucial aspect for fine-tuning operation reactor when inserted into closed-loop biorefinery at pilot-scale. ...

Based on Fluent software, a mathematical model of thermosyphon pump is established and numerical simulation carried out to study the influence riser tube length, diameter immersion ratio liquid lifting capacity efficiency. The results showed that: volume increased with increase ratio, whereas efficiency trend increasing followed by decreasing. highest for 340mm long, 6mm achieved when 0.35. Wit...

This volume originates from the Seventh International Conference on “Stochastic Models of Manufacturing and Service Operations”, which took place in Ostuni, Italy, in 7–12 June, 2009. The aim of this conference was to serve as a forum for researchers, academics and industrialists to discuss their most recent research findings and to provide them with opportunities for technology transfer. The c...

In recent times, the utilisation of marine composites in tubular structures has grown popularity. These applications include composite risers and related SURF (subsea umbilicals, flowlines) units. The industry evolved development advanced composites, such as thermoplastic pipes (TCP) hybrid structures. However, there are gaps understanding its performance risers, hence need for this review on d...

Floating, Production, Storage and Offloading &ldquo;FPSO&rdquo; have become a popular choice since 1980s for marginal and fast-track developments where subsea pipeline is not an economic or feasible solution for export. Field development usually starts with a concept selection procedure which is constituted from a sequence of multi-disciplinary decision making tasks. As limited data is availabl...

Abstract Free-standing hybrid risers are vertical slender steel pipes that commonly used in the oil and gas industry. These structures subjected to complex hydrodynamic loads results fatigue damage. The tidal forces develop on Freestanding Risers (FSR) with buoyancy cans ( BC ) because of varying outer pipe dimensions investigated this work. study considered riser diameters 0.2, 0.3, 0.5 0.6 me...
