In this study, three-dimensional flow measurements by means of 4D-Particle Tracking Velocimetry (4D-PTV) are carried out in a laboratory-scale 3 L stirred tank reactor order to investigate the flow-following behavior two different inertial particle types, Polyethylene (PE) particles and alginate beads, at impeller frequencies. Applied mimic Lagrangian sensor particles, which intended determine ...

Submarine pipelines are the lifelines of national economy. Under influence typhoons, high-speed currents and waves continuously erode seabed, leading to suspension or even rupture pipelines. Therefore, it is great importance study sediment transport under action currents. A numerical model scouring deposition combining wave established, which considered tidal current, storm surges, wind waves, ...

Buried pipes in the modern societies are considered as lifelines with a vital and essential role in the human life cycle. The performance of buried pipes is affected by many factors such as ground surface subsidence. In this paper, the effect of subsidence on pipelines is investigated using a three-dimensional numerical modeling developed in FLAC3D software for four types of most commonly used ...

With the advent of era big data, development models various sectors social economy have changed, and there are more market opportunities, but competition challenges also come along. As an important productive force in modern society, talent has become increasingly prominent digital process. Especially for state-owned enterprises, which essential lifelines pillars national economy, quality is ke...
