| 1 | On Nonlinear Evolution of C-type Instability in Nonparallel Boundary Layers显示文摘进化的过程,特别,非线性的进化,在 nonparallel 的 laminar 狂暴的流动转变的 C 类型不稳定性,边界层借助于一个最新发达的方法被学习,这叫了寓言的稳定性方程(PSE ) 。起始的条件,为非线性的问题很重要,被计算泛音波浪的起始的答案调查,修改 mean-flow-distortion,并且由解决线性 PSE 在起始的车站给 TS 波浪和它的次谐波波浪的起始的价值。有高顺序的精确性的一个数字方法在文章被开发,在 PSE 的关键正规化条件满足,并且非线性的 PSE 高效地被解决并且由空间前进稳定地实现了。在 Blasius 边界层的 C 类型不稳定性的非线性的进化的计算过程在对试验性的结果的好同意,这被显示出。 | Liu Jixue Tang Dengbin YangYingzhao | 2007 | Chinese Journal of Aeronautics2007，20，4： | 5 |
| 2 | Nonlinear evolution of turbulent spots in the near-wall shear flow显示文摘The initial model of turbulent spots with the wall disturbance using the pulse form was proposed. A group of three-dimensional coupling compact difference schemes with high accuracy and high resolution were developed, and implemented to simulate the formation and development of turbulent spots in the near-wall shear flow by means of direct numerical simulation of the Navier-Stokes equations. Growing and decaying modes were used to analyze nonlinear evolution characteristics of the turbulent spots. | ZHANG Li TANG Dengbin | 2006 | Science China(Physics,Mechanics & Astronomy)2006，49，2： | 3 |
| 3 | Evolution of the vortex structures and turbulent spots at the late-stage of transitional boundary layers显示文摘The nonlinear evolution process of new vortex structures at the late-stage of the transition, including the 3-D spatial structure of barrel-shaped vortex and 'dark spots' structure observed by experiment research, has been confirmed by our computational results. The formation mechanisms of these structures have been explored. It is revealed that the new vortex structures, the ring-like vortex chain and induced disturbance velocities play a dominant role in the generation of turbulent spots. | CHEN Lin TANG DengBin LU Ping LIU ChaoQun | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，5： | 3 |

| 6 | CALCULATION OF THREE DIMENSIONAL BOUNDARY LAYER EQUATIONS USING DIFFERENTIAL QUADRATURE METHOD显示文摘An extended differential quadrature method is used to compute nonlinear partial differential equations for tbree-dimensional laminar boundary layer now in this paPer. The key technique to differential quadrature, which is used in determining weighting coefficients for discretization of any order partial derivative, is investigated. The method of computing different weighting coefficients is presented. Three dimensional boundary layer equations are discretized by the differential quadrature method, and relative formula is obtained. The resulting scheme is applied to the computation of examples, which shows that the differential quadrature method can achieve rather high accurate solution using much less grid points than those of other methods, suck as finite difference and finite element methods. | Tang Dengbin Cheng Guowei(Department of Aerodynamics ,NUAA 29 Yudao Street ,Nanjing 210016,P.R.China) | 1994 | Transactions of Nanjing University of Aeronautics and Astronautics1994，11，1： | 0 |
