An efficient lignin depolymerization process with highly controllable product distribution was presented using metal chloride (MClx) cooperated with Pd/C.The catalytic performances of MClx were investigated.The effect of reaction conditions on the lignin depolymerization and products distribution were also studied.Results showed that more than 35.4% yield of phenolic monomer including 7.8% phenols and 1.1% guaiacols could beobtained under optimized condition.And the product distribution can be efficiently con-trolled by the modification of the metal cation through different pathway of Lewis acid catalysis and coordination catalysis.Furthermore, the Pd/C catalyst showed an excellent recyclability,whereno significant loss of the catalytic activity was exhibited after 3 runs.Moreover, the product control mechanism was proposed.

本文研究了5MW级水平轴风力机叶片内侧的风力机翼型的设计准则,设计了四种适用于该部位的大厚度钝尾缘翼型.依据一个5MW风力机的运行特征,对于不同的翼型设定不同的设计雷诺数;另一方面,其设计目标针对实际运行范围内的升力变化特征,并把升力随雷诺数变化的稳定性作为主要约束.翼型族经正反方法结合设计得到,RFOIL预测表明,四种翼型的升力系数在15°到30°攻角之间,其升力系数大致在1.0到1.7之间以近

传统水平轴风力机攻角调节采用航空器的机翼攻角调节理论,即最大升阻比理论.但是随着对风力机研究的不但深入,两者之间的差异不断显现出来,逐渐发现在最大升阻比状态下,风力机风能利用系数并不能达到最大.为了进一步提高风力机风能利用系数,本文应用叶素动量(BEM)理论对风力机传统攻角调节进行改进.发现适当减小攻角可以使风力机风能利用系数得到一定提高.针对三叶片NACA0012翼型水平轴风力机的算例进一步验证
