Eitch indented into the tube. Tube 48 was a clean copper tube that ad 50 longitudinal flutes pressed into the wall (Gener Electric double-flute profile, Diedrich, U.S. Patent 3,244,601, Apr. 5, 1966). Tubes 47 and 39 had a specially patterned porous sintered-metal deposit on the boihng side to promote nucleate boiling (Minton, U.S. [Pg.1046]

Experimental configuration and velocity profiles demonstrating the use of VISAR interferometric techniques in pressure-shear instrumentation to determine in-plane shear motion as well as longitudinal (P-wave) motion (Chhabildas and Swegle, 1980).

Thus, by using two VISARs, and by monitoring two beams at 6, both the longitudinal velocity and the shear-wave velocity can be determined simultaneously by solving the above two equations. With a lens delay leg VISAR (Amery, 1976), a precision in determining F(t) to 2% can be achieved. The longitudinal and transverse particle velocity profiles obtained in a study of aluminum are indicated in Fig. 3.12. [Pg.62]

Single chains confined between two parallel purely repulsive walls with = 0 show in the simulations the crossover from three- to two-dimensional behavior more clearly than in the case of adsorption (Sec. Ill), where we saw that the scaling exponents for the diffusion constant and the relaxation time slightly exceeded their theoretical values of 1 and 2.5, respectively. In sufficiently narrow slits, D density profile in the perpendicular direction (z) across the film that the monomers are localized in the mid-plane z = Djl so that a two-dimensional SAW, cf. Eq. (24), is easily established [15] i.e., the scaling of the longitudinal component of the mean gyration radius and also the relaxation times exhibit nicely the 2 /-exponent = 3/4 (Fig. 13). [Pg.587]

The plug flow reactor has a flat velocity profile and no longitudinal mixing. These idealizations imply that all fluid elements leaving the reactor have the same age (T). The F(t) function for this system must then be... [Pg.392]

This problem indicates the considerations that enter into the design of a tubular reactor for an endothermic reaction. The necessity of supplying thermal energy to the reactor contents at an elevated temperature implies that the heat transfer considerations will be particularly important in determining the longitudinal temperature profile of the reacting fluid. This problem is based on an article by Fair and Rase (1). [Pg.540]

Pi Each pi bond has one axial nodal plane (p-like shape) and the longitudinal profile, (Figs. 4.24(b) and (c)) to be expected from 7t-type overlap of d orbitals. The two pi bonds are labeled 7tw(o) (out of plane) or 7Tww(l) (in plane) to distinguish their orientation with respect to the molecular plane. [Pg.416]

The hydraulic models require topographic information in the form of the stream s longitudinal profile and channel cross-sections at several locations. [Pg.199]

However, the two mechanisms interact and molecular diffusion can reduce the effects of convective dispersion. This can be explained by the fact that with streamline flow in a tube molecular diffusion will tend to smooth out the concentration profile arising from the velocity distribution over the cross-section. Similarly radial dispersion can give rise to lower values of longitudinal dispersion than predicted by equation 4.39. As a result the curves of Peclet versus Reynolds number tend to pass through a maximum as shown in Figure 4.6. [Pg.209]

Nishino (1991) noted the presence of an induction period in the kinetic profile of reactions of solid wood samples with acetic anhydride vapour. The duration of this induction period decreased and the rate of reaction increased with both increasing temperature and concentration of acetic anhydride vapour in the reaction vessel (Nishino, 1991). The rate of reaction was diffusion limited, with the rate of diffusion being greatest in the longitudinal direction of the wood samples. This phenomenon is only found in solid wood samples, since no induction period was noted for the reaction of wood fibres with acetic anhydride vapour (Loras, 1968). [Pg.50]

Without the external field, the Stockmayer fluid near the wall exhibits symmetric density oscillations that die out as they reach the middle of the film. Near the surface, the fluid dipoles are oriented parallel to the walls. Upon turning on the electric field, the density profile of the Stockmayer fluid exhibits pronounced oscillations throughout the film. The amplitude of these oscillations increases with increasing field strength until a saturation point is reached at which all the fluid dipoles are oriented parallel to the field (perpendicular to the walls). The density profile remains symmetric. The dipole-dipole correlation function and its transverse [] and longitudinal [] com-... [Pg.139]

Different longitudinal sections in the structure may generally have very different refractive index profiles, and thus their eigenmode functions can strongly differ, too. As they have to be well-represented by the superposition of modes of other sections, the number M of considered eigenmodes needs to be sufficiently large (typically from tens to hundreds), and it means that many of these modes are evanescent in the direction of propagation (for their effective indexes, Re lV < 0). [Pg.81]
