When the buried pipeline is subjected to external explosion load, stress and deformation will occur. value exceed a specific range, it affect normal use of pipeline. In this paper, multiphase coupled model pipeline, soil fluid within established. The penalty function coupling method used describe load between By specifying boundary conditions system, global solution variational principle soil-p...

Abstract Pipeline transportation is a process of continuous balance between pumping pressure and pipeline resistance. Therefore, accurate calculation resistance can optimize the accuracy pump model working parameters. The slurry transported in dredging project complicated, dredged soil different regions quite resulting motion states process. Different types flow patterns are suitable for models...

Large deformation causing damage due to uplift force is generated in buried pipeline located in shallow trenches in marshes and saturated soils. In this paper, existing common methods of pipeline anchorage are discussed and considering advantages and disadvantages of these methods, a new method of pipeline anchorage are studied and presented. In this new developed method, geo-textile materials ...

Wan Carbon capture and sequestration (CCS) is an important option for CO2 mitigation and an optimized CO2 pipeline transport system is necessary for large scale CCS implementation. In the present work, a hydrodynamic ...

Three-dimensional (3D) image acquisition systems are rapidly becoming more affordable, especially systems based on commodity electronic cameras. At the same time, personal computers with graphics hardware capable of displaying complex 3D models are also becoming inexpensive enough to be available to a large population. As a result, there is potentially an opportunity to consider new virtual rea...
