- Prediction of hydrodynamic performance of highly skewed propeller
大侧斜螺旋桨水动力性能预报 - There are 2 - 3 layers of long - column - shaped palisade tissue under the upper epidermis , and there are a great number of mechanical tissues which made up of vascular bundle sheath
上表皮下方有2 - 3层长柱形的栅栏组织，在主脉大侧脉外方具有由大量机械组织组成的束帽或束鞘。 - Whereas , vdsc operates on physical limits of large vehicle slip angle and lateral acceleration , and enhances vehicle lateral stability by utilizing the additional yaw moment produced by different adhesion forces acted on the right and left side wheels
而vdsc系统主要在车辆大侧向加速度、大侧偏角的极限工况下工作，通常利用左、右两侧车轮附着力之差产生的横摆力矩来达到稳定性控制目的。 - They have also been exported to iran , china , india , poland , romania and algeria . china has two type 636 submarine which are designed for antisubmarine and anti - surface ship asuw warfare as well as for general reconnaissance and patrol missions
636型潜艇是在877型的基础上又进行了改进提高，其降低动力装置的转速，采用了七叶大侧斜螺旋桨，增大充电功率提高了充电能力，改进降噪措施，进一步降低了噪声。 - The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller . the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution . for highly skewed propeller , the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface , which result easily in incorrect calculation results of velovity on blade surface , even in iteration divergence and calculation failure . a “ non - conventional grid ” is developed to acoid these problems . this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller . the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure . by sample calculating , the obtained results are satisfied the experimental data
采用面元法预报大侧斜螺旋桨水动力性能，螺旋桨表面及尾涡面离散为四边形双曲面元，每个面元上布置等强度源汇和偶极子分布.对于大侧斜螺旋桨而言，桨叶表面采用常规的等半径网格划分方法在近叶梢处将导致大展弦比、大侧斜和扭曲面元，这容易使桨叶表面速度的计算结果不正确，甚至会导致迭代过程发散及计算失败.文中建立了一种“非常规网格”划分方法，能有效地解决大侧斜螺旋桨的计算和收敛问题.桨叶随边处通过迭代实现非线性等压库塔条件
