全断面双护盾掘进机在引黄工程断层破碎带的卡机处理

万家寨引黄工程国际Ⅱ、Ⅲ标已查明的断层有34条，隐伏断层可能还有一些，除了利民堡区域性大断层（F32）外，较大的集中于7#洞北段59＋700—68＋820，主要有F65、F70、F90、F74。全断面双护盾掘进机适应于较复杂的地质条件，因此在通过断层破碎带时一般都较正常。但在通过引黄工程区域性大断层F65时，发生了卡机事故，处理用了3个月时间。该文对处理TBM卡机事故的施工进行了总结。

Experimental and computational analysis on guide vane losses of impulse turbine for wave energy conversion

This paper deals with the detailed flow analysis of impulse turbine with experimental and computed results for wave energy power conversion. Initially, several turbulence models have been used in two-dimensional (2-D) computational fluid dynamic (CFD) analysis to find a suitable model for this kind of slow speed unconventional turbine. Experiments have been conducted to validate the CFD results and also to analyze the aerodynamics at various stations of the turbine. The three-dimensional (3-D) CFD model with tip clearance has been generated to predict the internal flow and to understand the effect of tip clearance leakage flow on behavior of the turbine in design and off-design conditions. As a result, it is found from the 2-D results that the comparison between computed and experimental data is good, qualitatively and the turbulence model, standard k–ε can predict the experimental values reasonably well, especially the efficiency of the turbine. Experimental results reveal that the downstream guide vanes are more responsible for low efficiency of the turbine and it is measured that 21% average pressure is lost due to downstream guide vanes. It is proved from the 3-D CFD model with tip clearance that it can predict the experimental values quantitatively and qualitatively. Furthermore, it is estimated from the computed results that the efficiency of the turbine has been reduced about 4%, due to tip clearance leakage flow at higher flow coefficients.
