High Level Synthesis for Packet Processing Pipelines

Dynamic Pressure rise or fall in all kinds of pipelines due to the operation valve which are transmitting fluids very much essential part consider design pipeline. This paper presents how calculate these dynamic pressure waves while designing pipelines.

Slugging flow in offshore oil & gas multi-phase transportation pipelines cause big challenges as the flow regime induces flow and pressure oscillations in the multi-phase pipelines. The negative impacts of the most severe slugs are significant and thus the elimination of slugging flow in the pipelines is a highly investigated topic. To eliminate the slug in an online manner real-time slug detec...

In this work, collapse of corroded pipeline under combined external pressure and tension is investigated through numerical method. Axially uniform corrosion with symmetric imperfections is firstly considered. After verifying with existing experimental results, the finite element model is used to study the effect of tension on collapse pressure. An extensive parametric study is carried out using...

Abstract Onshore high - pressure gas pipelines constitute critical infrastructure that usually cross seismic prone regions and are vulnerable to Permanent Ground Deformations (PGDs) due active faults. In design, it may not be feasible avoid fault rupture areas various technical, economical topographic reasons. Moreover, the presence of soil layers affects PGDs resulting from a tectonic fault, w...

nowadays one of the most important energy sources is natural gas. by depletion of oil reservoirs in the world, natural gasâ will emerge as the future energy source for human life. one of the major concerns of gas suppliers is being able to supply this source of energy the entire year. this concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...
