This paper derives analytical solutions for steady-state one-dimensional (1-D), two-dimensional (2-D), and three-dimensional (3-D) two-phase immiscible subsurface flow for a counter-current problem. Since the governing equations are highly nonlinear, 2-D and 3-D derivations are generally ...
Moreover, only the flow field downstream of these directions is altered by the disturbance; there is no effect on the upstream flow. In a two-dimensional or axisymmetric flow, these directions are referred to as Mach lines or characteristics. In a three-dimensional flow, the Mach lines become...
Three-dimensional natural convective flow in a rectangular enclosure with vertical sidewalls and horizontal top and bottom surfaces has been considered. A heated rectangular element is mounted in the middle of one vertical wall of the enclosure, the remainder of this wall being adiabatic. The remaini...
摘要: WE are studying the spatially periodic chemical reactions that have been observed in initially homogeneous solutions1-4, and have found that the origins of one, two and three-dimensional spatial periodicities are different.DOI: 10.1038/physci235015a0 被引量: 12 ...
Desculpa [translate] aOne-dimensional flow of a pure fluid flashing along a pipe is considered (Fig. 2). This flow is assumed to satisfy the following basic hypothesis: 闪动沿管子的纯净的流体的一元流被考虑(。 2). 这流程假设满足以下基本的假说: [translate] ...
two dimensional up-and-down method under dfifferent probability of failure and believe.The result shows that the relative deviation of fatigue strength using one dimensional method is much 3 to 4 times larger than two dimensional method.In addition,more experienced data brings more accurate result....
The utility model discloses a three-dimensional translational and one-dimensional rotational parallel mechanism, which comprises a holder, a moving platform and four branch links, wherein the branch links the same in structure are disposed between the holder and the moving platform. The moving platfo...

In brief, single mEos2 fluorescent peaks were identified in each frame and fit by a two-dimensional Gaussian function to extract spatial coordi- nates and the number of photons. Peaks with brightness below 63 photons were discarded. The majority of peaks were localized with a spatial precision...
