提出了基于束传输法(BPM)的大孔径光纤锥形过渡器理论分析模型。讨论了过渡器在纵向边界线性和非线性情况下(包括类似正弦型和余弦型变化),分别以大小端作为输入端口,耦合角度以及耦合长度对过渡器的损耗和耦合效率的影响,得出了过渡器最佳纵向边界、耦合角度和耦合长度。

在含水复杂的地质条件下采用水平冻结法进行盾构进出洞施工,可以通过延长(加深)水平冻结外圈冻结深度,使冻结加固体全方位包裹并超过盾构机本体,利用外圈冻结孔的维护冻结,将盾构推进过程中形成的微小流水通道中的泥土冻结成为冻土,封闭流水通道,较为有效地防止了流水、涌砂现象的发生。利用长距离水平钻孔防喷接驳器,简单方便地解决了在已施工完毕的端头井内长距离钻孔的难题。工程实践证明,全方位风险控制冻结加固技术在复杂地质条件下盾构进出洞施工中,简单易行,安全可靠,值得推广应用。

The magnitude and stability of power output are two key indices of wind turbines. This study investigates the effects of wind shear and tower shadow on power output in terms of power fluctuation and power loss to estimate the capacity and quality of the power generated by a wind turbine. First, wind speed models, particularly the wind shear model and the tower shadow model, are described in detail. The widely accepted tower shadow model is modified in view of the cone-shaped towers of modern large-scale wind turbines. Power fluctuation and power loss due to wind shear and tower shadow are analyzed by performing theoretical calculations and case analysis within the framework of a modified version of blade element momentum theory. Results indicate that power fluctuation is mainly caused by tower shadow, whereas power loss is primarily induced by wind shear. Under steady wind conditions, power loss can be divided into wind farm loss and rotor loss. Wind farm loss is constant at 3α(3α−1)R2/(8H2). By contrast, rotor loss is strongly influenced by the wind turbine control strategies and wind speed. That is, when the wind speed is measured in a region where a variable-speed controller works, the rotor loss stabilizes around zero, but when the wind speed is measured in a region where the blade pitch controller works, the rotor loss increases as the wind speed intensifies. The results of this study can serve as a reference for accurate power estimation and strategy development to mitigate the fluctuations in aerodynamic loads and power output due to wind shear and tower shadow.
