拟序结构 meaning in English
coherent structure
Examples
- Diretct numerical simulation in turbulent coherent structures of three - dimensional gas - particle two - phase mixing layer
三维气固两相混合层湍流拟序结构的直接数值模拟 - Bifurcation is a common nonlinear phenomenon and plays an important role in the nonlinear science . in this thesis , we concentrate on analysis and computation of bifurcation . it can be separated as two parts on the whole
分歧是一种常见的非线性现象，并与其它非线性现象(如混沌、湍流、突变、分形、拟序结构等)密切相关，在非线性科学的研究中占有重要地位。 - In addition , the vortex structures of the gas flow field and particle dispersion were studied when the coupling action between the two phases was considered in the case of different mass loading of mediate stokes number particles was provided in the gas - particle plane jet
另外，文中还模拟研究了气粒两相平面射流中不同质量携带率下中等stokes数颗粒与气相流场的相间耦合作用下气相流场的旋涡拟序结构以及颗粒运动扩散规律。 - At the same time , dispersion of different stokes number particles influenced by the ordered large - scale turbulent structures of the carrier gas phase was investigated . and the following " conclusion was drawn : particles of mediate stokes number mainly concentrated in the outer boundary region of large scale eddies , and they had the nignest dispersion rate ; particles or little stakes number mainly lay in the core region of the eddies , and they had the lest dispersion rate ; though particles of large stokes number distributed throughout the eddy structures
同时还模拟研究了不同stokes数颗粒在二维流场旋涡拟序结构作用下的运动扩散特性，详细描述了不同stokes数颗粒在流场中的空间分布规律，认为：中等stokes数颗粒集中于流场旋涡的外沿区域，在流场空间中的扩散率最高；小stokes数颗粒集中于流场系列旋涡的涡核区域，在流场空间中的扩散率最低；而大stokes数颗粒则遍布于流场旋涡涡核和涡外沿区域。 - The results show the moment developing course of flow over flat wall and the evolvement of coherent structure , and also completely simulate all kinds of detail processes in development of boundary layer over flat wall , such as the generation and rise of low - speed stream , the extension and rupture of horse - hoof - shaped vortex and so on
模拟结果给出了平壁流动的瞬态发展过程以及流动中拟序结构的发展演变过程，成功地模拟了平壁边界层发展中的各种瞬态细节过程，如低速条带的产生、上举过程，马蹄形涡的拉伸变形、破裂过程。
