Radial movement

A particle entering the cyclone finds a poiat where its velocity with respect to the fluid is equal to the radial velocity, and hence is at rest with respect to radial movement to or from the wall. Because the radial velocity changes with radius, the particle spirals down the cone section, foUowiag a path defined... [Pg.437]

Excessive radial movement can cause wear, fretting, or pitting of the shaft packing or secondary sealing element at the point of contact between the shaft packing and the shaft or sleeve OD. [Pg.951]

OS 92] [R 32] [P 72] For radial movement from a center position, wave splitting was found [68]. Two new reaction zones were formed from a part of the circular reaction zone (Figure 4.100). [Pg.561]

In contrast, flat-blade stirrers and turbines mainly cause radial movement (see Figs. 5.4-5 and 5.4-6). An anchor is used to enhance heat transfer between the reaction mixture and the cooling medium. [Pg.264]

Figure 7.2(b) shows the radial movement of solution over the face of the disc during rotation these lines of flow are sometimes called streamlines. [Pg.201]

Platelet attachment to subendotheliumf is determined predominantly by physical factors controlling the rate of platelet transport to the subendothelium at low shear rates (800 s ). In addition, platelet deposition was found to be highly dependent on the concentration of red cells, an effect attributed in part to the fact that red cells, by increasing the radial movement of platelets, enhance their diffusivity by several orders of magnitude compared to that theoretically predicted and experimentally measured in platelet-rich plasma. [Pg.384]

A model of transfer within an oscillating droplet was proposed by Handlos and Baron (H3). They assumed that transfer within the drop was entirely by turbulent motion, random radial movement, superimposed upon toroidal circulation streamlines. No allowance was made for the variation of shape or... [Pg.198]

CTTS transitions in coordination compounds result in a radial movement of electron density from the metal to the surrounding solution medium. The energies of these transitions generally are very sensitive to environmental parameters such as solvent polarity, temperature and the presence of salts.104 This sensitivity has been used in a diagnostic sense to identify CTTS bands in the spectra of anionic cyanide complexes105 and 1,2-dithiolene complexes of Ni, Pd and Pt.106 Hydrated cations such as Cr2+(aq) and Fe2+ (aqj exhibit absorption bands that are sometimes referred to as CTTS in character. Since the solvent occupies the first coordination sphere of the metal, however, the distinction between CTTS and CTTL transitions in these systems becomes obscured. [Pg.405]

Here the quantity U is an effective potential that contains three contributions the kinetic energy for the radial movement of the electrons (in the coordinate a), a centrifugal potential energy, and the Coulomb potential energy — C(a, 12)/R of the system. In the present context of double photoionization it is this Coulomb energy which determines the features of two-electron emission (in atomic units) ... [Pg.258]

For a point source, z is zero, and from equ. (10.6b) it follows that tp = const. This means that the electrons ejected from the source move in a plane which contains the z-axis. Hence, the focal point must also be in this plane, and this fact considerably facilitates the discussion of the optical properties of the spectrometer. Due to the conservation conditions, one is left with only one differential equation which describes the radial movement of the electron, i.e.,... [Pg.379]

Accumulation of fructans is enhanced by high light intensity and moderate temperatures. It is reduced by excess nitrogen or insufficient potassium (Soja and Haunold, 1991). Distribution of assimilates initially occurs on the periphery of the stem with subsequent movement inward. The portion of the stem receiving assimilates is dictated by its vascular connections. Radial movement inward is restricted to cells interior to vascular bundles. [Pg.304]

The dependence of Ych on the deuterium flux density has not yet been clarified sufficiently well. A summary of various published data of the CD4 yield is displayed in Fig. 1.5a as a function of the flux density of the back ground plasma (deuterium) [6,26]. The flux variations have been obtained either by density scans or for the limiter cases (TEXTOR) by a radial movement of the limiters. These published data suffer from some inconsistencies due to different experimental conditions (electron temperature, surface temperature). The photon efficiency from which particle fluxes are derived [27] depends on the electron temperature. The chemical reactivity [6] depends... [Pg.14]

From the analysis of the decomposition of the images, we can observe that the movement ahead is dominant and controls the whole displacement. In the example given in Fig. 4.8, we can observe that the movement ahead (elementary state or process component) presents approximately the same frequency as the backward displacement. A radial movement is also possible but can be neglected if we consider only a very thin band in the centre of the bed. The same has been consid-... [Pg.207]

The counter is left in its usual position on the diffractometer circle (no radial movement) for the inclined measurement. The diffracted beam is then poorly focused at the counter and the intensity at the counter slit is decreased, but there is no need for a radial slide on the diffractometer. [Pg.465]

Kinesins can be divided into two broad functional groups— cytosolic and mitotic kinesins—on the basis of the nature of the cargo that they transport (Table 20-2). The functional differences between kinesins are related to their unique tall domains, which determine their cargoes. Cytosolic kinesins take part in vesicle and organelle transport they Include the classic axonal kinesin I, which has been shown to transport lysosomes and other organelles. Some cytosolic kinesins, however, transport one specific cargo. For example, KIFIB and its close relative KIFIA transport mitochondria and synaptic vesicles, respectively, to nerve terminals. Other cyrt osollc kinesins mediate the transport of secretory vesicles to the plasma membrane and the radial movement of ER... [Pg.832]
