AR = cavity aspect ratio a = speed of sound b = cavity half-width ~ C = dynamic compressibility c = phase speed cp = specific heat at constant pressure f = frequency H = cavity depth k = wave number m = propagation constant P = pressure Pr = Prandtl number R = reflection coefficient p = acoustic pressure pi = initial pulse amplitude Re = acoustic Reynolds number s = cavity spacing T = temperatu...
We propose a framework for the spectral processing of tangential vector fields on surfaces. The basis is a Fourier-type representation of tangential vector fields that associates frequencies with tangential vector fields. To implement the representation for piecewise constant tangential vector fields on triangle meshes, we introduce a discrete Hodge–Laplace operator that fits conceptually to th...
We discovered strong gravitational lensing in 4 galaxy clusters by visual inspection of the Sloan Digital Sky Survey images in Data Release 6 (SDSS DR6). Two of them show the Einstein rings, and the other two show tangential giant arcs. These arcs or rings have large angle separations of > 8 from the bright central galaxies. The lensed images in general are bluer than cluster member galaxies. T...
in this paper it is attempted to investigate the behavior of an inviscid flow in the meridional plane of an axial flow compressor. for this purpose the 3-d unsteady euler equations in cylindrical coordinate are averaged in tangential direction. therefore, the equations are reduced to a 2-d system. by averaging the tangential component of momentum equation, a blade force will result. axial and r...
This paper seeks to examine aspects of tangentiality connecting heritage tourism goals, on the one hand, and museum architecture, other. It does so through specific angle communication, understood as a complex process that fluctuates, very large extent, at level external conventional institutional practice. The assumption is determining factors are in fact tangential nature that, contrariwise, ...
OBJECTIVE To evaluate the intraobserver and interobserver reliability of radial torsion angle measurement using computed tomography. METHODS Twelve pairs of cadaver radii and 116 forearms from 58 healthy volunteers were evaluated using axial computed tomography sections measured at the level of the bicipital tuberosity and the subchondral region of the radius. During digital imaging, the angl...
Abstract For a drill bit, the cutter is most important part to break rock. In oilwell drilling, polycrystalline diamond compact (PDC) bit widely used shear rock formation. this paper, finite element model with including axe-shaped PDC and formation developed study breaking behaviours. Results show that effect of on better than planar cutter. The front rake angle face angel play significant role...
The boundary behavior of axisymmetric microswimming squirmers is theoretically explored within an inertialess Newtonian fluid for a no-slip interface and also a free surface in the small capillary number limit, preventing leading-order surface deformation. Such squirmers are commonly presented as abridged models of ciliates, colonial algae, and Janus particles and we investigate the case of low...
cumulus parameterization in numerical weather prediction models can significantly affect severe weather forecasts, such as hurricanes, flash floods, and winter storms. the role of convection is essential in stabilizing an unstable atmosphere through vertically transferring moisture, energy, chemical species and momentum. cumulus parameterization schemes use simple one-dimensional convective clo...
