JOURNAL OF FLUID MECHANICS 1994年 274卷 115-138页
作者: SMITH, LM YAKHOT, V Program in Applied and Computational Mathematics Princeton University Princeton NJ 08544 USA Present address: Department of Mechanical Engineering Yale University New Haven CT 06520 USA
A new mechanism for the creation of structures in two-dimensional turbulence is investigated. The forced Navier-Stokes equations are solved numerically in a periodic square in the limit of zero viscosity. The force is... 详细信息

CELESTIAL MECHANICS & DYNAMICAL ASTRONOMY 1994年 第1期60卷 3-28页
作者: LIU, J SUN, YS Institute of Applied Physics and Computational Mathematics Beijing P.R. of China Department of Astronomy Nanjing University Nanjing P.R. of China
There exist many comets with near-parabolic orbits in the Solar System. Among various theories proposed to explain their origin, the Oort cloud hypothesis seems to be the most reasonable (Oort, 1950). The theory assum... 详细信息

THE BREAK-UP OF A HETEROCLINIC CONNECTION IN A VOLUME PRESERVING MAPPING
收藏 引用
PHYSICA D 1993年 第1-4期62卷 51-65页
作者: ROMKEDAR, V KADANOFF, LP CHING, ESC AMICK, C Computational and Applied Mathematics Program The Department of Mathematics The University of Chicago Chicago IL 60637 USA
We consider a family of three-dimensional, volume preserving maps depending on a small parameter epsilon. As epsilon --> 0+ these maps asymptote to flows which attain a heteroclinic connection. We show that for sma...
