Simulation on Flow Field Characteristic of Restricted Wall-attached Jet in Heading Face

Wang Haiqiao,Liu Ronghua,Chen Shiqiang

Strategic Study of CAE 2004, Volume 6, Issue 8,   Pages 45-49

Abstract:

Pressed ventilation in heading face is actually a restrained wall-attached jet ventilation in confined space. In this paper, based on hydrcxlynamic and jet theory, the turbulence k-ε model of restrained wall-attached jet ventilation in heading face is set up and calculation boundary is analyzed. Combining with practice, and using PHOENICS3. 4 software of computational fluid dynamics (CFD), three - dimensional airflow field of the jet ventilation in heading face is simulated. The flow field characteristics such as the flow field zoning, the starting segment of jet, the attaching course of jet and the changing pattern of jet velocity are obtained by numerical simulation. According to result of numerical simulation, there are four zones in heading face, i. e. wall-attached jet zone, impact jet wall-attached zone, back flow zone and eddy zone. The starting segment length of attached jet is shorter than thar of free attached jet. After wall-attached jet formed completely, the axis velocity of wall is higher than that in air outlet. The result of numerical simulation agrees with that of experiment, which provides a dependable basis for further study of the air mass transport process, the reason of methane accumulation and the efficiency of air displacement in heading face.

The research of connectivity-credibility restricted clustering algorithm in wireless sensor networks

Yu Jiming,Sun Yamin,Lei Yanjing,Yang Yuwang

Strategic Study of CAE 2010, Volume 12, Issue 9,   Pages 73-77

Abstract:

This paper proposed a speeding clustering algorithm of connectivity-credibility constrained random dispose which based on some other clustering algorithms. Simulation shows that this algorithm can get large cover of clustering, logical distributing and good stability. Comparing to the lowerst-ID clustering and highest-connectivity clustering algorithm, the algorithm can get less number of cluster-heads, more logical clustering, good communication between nodes and cluster-heads, steady networks, reduce communication cost of rebuilding, and can balance network's energy consume, prolong the networks life.

Key Technologies of the Hydraulic Structures of the Three Gorges Project

Xinqiang Niu

Engineering 2016, Volume 2, Issue 3,   Pages 340-349 doi: 10.1016/J.ENG.2016.03.006

Abstract:

To date, the Three Gorges Project is the largest hydro junction in the world. It is the key project for the integrated water resource management and development of the Changjiang River. The technology of the project, with its huge scale and comprehensive benefits, is extremely complicated, and the design difficulty is greater than that of any other hydro project in the world. A series of new design theories and methods have been proposed and applied in the design and research process. Many key technological problems regarding hydraulic structures have been overcome, such as a gravity dam with multi-layer large discharge orifices, a hydropower station of giant generating units, and a giant continual multi-step ship lock with a high water head.
