| 1. | Blade profile drag coefficient 桨叶剖面阻力系数 |
| 2. | Chinese dragon two handed jian was not made after the early two handed jian because the blade profile and cross section were different from the period pieces 中国卷双手剑并不是依照以上两代的双手剑制作,因为刃的横切面及型态均与当时的双手剑不同。 |
| 3. | In addition to the standard galvanized product , we are also able to manufacture both blade profiles in stainless steel or various other material on special request 产品已被世界各国用户认可并批量使用,并且许多发达国家更把不锈钢刀片刺网系列做为防护用品的首选。 |
| 4. | The idea of the design method throws off the reliance on the engineering experience , avoids complicated special transformation , and has the blade profile and impeller optimized 本文的设计思想,减少了对工程经验的依赖,避免了复杂的空间转换,可使叶型和叶轮得到优化。 |
| 5. | The design method proposed in this paper is , in principle , based on the potential - stream function inverse method , using numerical optimization to obtain optimized blade profiles 本文是在反方法叶型设计的基础上,采用优化方法有效调节给定的初始速度分布来获得优化叶型。 |
| 6. | Finally , the five kinds of blade profiles of splitter blades were designed by the software of bladegen . the grid generation and cast for the splitter blades were completed and all the results were compared with fluent 在两组不同的出口反压下,不仅用本文的程序分别对其进行了网格生成和计算,而且还与fluent软件计算的结果进行了相应的对比和分析。 |
| 7. | There are three kinds of tandem cascades : the axial gap of the first one was zero , the french blade profile of onera was seiected . casting the flow field at five disparate flow tuming angles , and some analysis and comparison were completed <中文摘要> =本文对三种不同形式的串列叶栅以及大小叶片分别进行了网格生成,并对其流场进行了计算和分析。 |
| 8. | These cut - outs can be made in either of the two blade profiles we manufacture , medium or short barb . in addition to the standard galvanized product , we are also able to manufacture both blade profiles in stainless steel or various other material on special request 刀片用及耐腐蚀性的热镀锌钢板或不锈钢板做材料,由专用机械强力包附在热镀锌高碳钢丝或不锈钢丝做的芯线上。 |
| 9. | The flows in the case of different reduced frequencies are computed respectively for two blade profiles . by comparing the time curves of relative parameters in oscillating cascades and the flow field contours under different conditions , it is indicated that the reduced frequency is an important factor to determine whether the blade flutter happens or not 针对两种叶型分别计算了不同折合频率下的流场,通过比较振动叶栅相关参数随时间变化的曲线及流场云图,表明折合频率是决定叶片颤振与否的重要因素。 |
