A computational and experimental study is reported of turbulent flow around a square-sectioned U-bend with a mean bend radius equal to 3.375 times the hydraulic diameter (DH): the duct Reynolds number is 58,000. The bend geometry is the same as that for which Chang et al. (1983) have reported extensive LDA data except that in the latter experiment the bend was preceded by some thirty hydraulic ...

In general, superbiharmonic functions do not satisfy a minimum principle like superharmonic functions do, i.e., functions u with 0 ≡ ∆u ≥ 0 may have a strict local minimum in an interior point. We will prove, however, that when a superbiharmonic function is defined on a disk and additionally subject to Dirichlet boundary conditions, it cannot have interior local minima. For the linear model of ...

Contractional deformation is common along transform plate margins where motion oblique to the boundary. While faults that accommodate this are often inferred be subsidiary main boundary fault, we typically lack direct geometric or kinematic information. Here investigate timing of faulting relative changes in orientation North American-Pacific Coeval with development an segment (i.e., “Big Bend”...
