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.

An Enhanced Physically Based Scour Model for Considering Jet Air Entrainment

Rafael Duarte,António Pinheiro,Anton J. Schleiss

Engineering 2016, Volume 2, Issue 3,   Pages 294-301 doi: 10.1016/J.ENG.2016.03.003

Abstract:

Based on systematic experiments on the influence of air entrainment on rock block stability in plunge pools impacted by high-velocity jets, this study presents adaptations of a physically based scour model. The modifications regarding jet aeration are implemented in the Comprehensive Scour Model (CSM), allowing it to reproduce the physical-mechanical processes involved in scour formation concerning the three phases; namely, water, rock, and air. The enhanced method considers the reduction of momentum of an aerated jet as well as the decrease of energy dissipation in the jet diffusive shear layer, both resulting from the entrainment of air bubbles. Block ejection from the rock mass depends on a combination of the aerated time-averaged pressure coefficient and the modified maximum dynamic impulsion coefficient, which was found to be a constant value of 0.2 for high-velocity jets in deep pools. The modified model is applied to the case of the observed scour hole at the Kariba Dam, with good agreement.
