In-Situ Test Method for Hydrodynamic Characteristics of Water Flowing Around Piles
نویسندگان
چکیده
The dynamic characteristics of the flow around pile directly determine distribution law force on pile, which is basis calculation load hydraulic structure. At present, model test and numerical simulation methods are mainly used to study pile. There problems scale effect accuracy in laboratory test, inherent method, such as determination medium parameters, mesh division, boundary conditions. Therefore, research results cannot reflect actual situation interaction between water This paper developed a field system for measuring hydrodynamic pressures surface piles vital foundations wharves under superhigh Reynolds number. And analysis in-situ data, can realize multifunction including calibration transformation frequency time-domain statistical process, were put forward according theory stationary random process mathematical statistics method. A representative frame wharf located upper reaches Yangtze River was performed case study, utilized operate this practice. Application showed that be applied obtain more accurate pressure. drag coefficient ranged from 0.30 0.40. These findings may provide significant technical support similar structures some reference engineering design.

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
In-channel focusing of flowing microparticles utilizing hydrodynamic filtration
We present herein microfluidic systems to continuously focus the positions of flowing particles onto the center of a microchannel, which is indispensable to various applications for manipulating particles or cells such as flow cytometry and particle-based bioassay. A scheme called ‘hydrodynamic filtration’ is employed to repeatedly split fluid flows from a main stream, while remaining particles...
متن کاملAnalysis of Consolidation around Driven Piles in Overconsoli Dated Clay
The principal objective of this thesis is to assess the capabilities of an already established analytical framework for understanding and predicting the behavior of piles driven in highly overconsolidated clays (OCR24). The skin friction mobilized during pile loading to failure depends on the sequence of preceding events, i.e. pile installation and soil consolidation. This research utilizes the...
