High Pressures. Thermosyphon reboilers present design problems at the two extremes of the pressure scale. Near the critical pressure, the maximum allowable flux drops. [Pg.304]

Figure 4.1. Sketch of LES energy spectrum with the sharp-spectral filter. Note that all information about length scales near the Kolmogorov scale is lost after filtering. [Pg.124]

Length scales near the wall are strongly influenced by the jet and depend only weakly on the distance to the wall. [Pg.139]

The Monte-Carlo solvers developed for transported PDF methods are highly paral-lelizable and scale nearly linearly on multiprocessor computers. [Pg.259]

From Table VIII—1B and JQj of Fig. VIII-7, re,(03) is calculated as a function of altitude. This relationship is shown in Fig. VIII—9. The equilibrium time scale near the top of the stratosphere is about a day, while below 15 km Te (Oj) more than a year and downward physical transport processes of 03 become important. [Pg.256]

These considerations highlight the fact that microdialysis and voltammetry, particularly fast-scan cyclic voltammetry, estimate two quite different aspects of DA transmission characterized by different temporal and spatial constants. Microdialysis estimates steady-state levels of extracellular DA and changes in these levels taking place on a minute scale away from DA release sites. Fast-scan voltammetry estimates changes in DA-like signals taking place on a subsecond scale near DA release sites. [Pg.347]

More reliable estimates of monomer reactivity are available from reactions of model compounds (Chapter 2). For example, the rate constants of addition of the same standard benzhydryl carbenium ion to various substituted styrenes correlate very well to Hammett s + = 4.9 [193]. Addition of various p-substituted benzhydryl cations to the same standard alkene yielded p(Acr = — 5.1 [193]. These results demonstrate that carbocationic polymerizations are extremely sensitive to even small changes in the monomer structure. They also demonstrate that the reactivity of carbenium ions scales nearly perfectly to the... [Pg.223]

Solution A line drawn through 100 on the -scale and 33 on the R-scale intersects the C-scale near 0.02. Thus, a 0.02-/rF capacitor would be satisfactory for the 100-V/33-X1 combination. Notice that this same R-C combination would be proper also for a 20-V circuit. [Pg.91]

For turbulent kinetic energy, k, the normal gradient at the wall is usually set to zero. By assuming the length scale near the wall, L to be given by ... [Pg.75]

Scaling near a homoclinic bifurcation) To find how the period of a closed orbit scales as a homoclinic bifurcation is approached, we estimate the time it takes for a trajectory to pass by a saddle point (this time is much longer than all others in the problem). Suppose the system is given locally by x x, y = -2, y. Let a trajectory pass through the point (/i,l), where f.i 1 is the distance from the stable manifold. How long does it take until the trajectory has escaped from the saddle, say out to x t 1 (See Gaspard (1990) for a detailed discussion.)... [Pg.293]

The relation A7 oc Rq obtained from the Ginzburg-Pitaevskii-Sobyanin theory for a finite system is related to the theory of second-order phase transitions with the experimental critical parameter, v = 0.67, for the superfluid fraction and for the correlation length scaling near the critical point of infinite systems [155, 193-197, 199]. This theory implies that the intensive properties of a system of size L(= Rq) depend on the ratio L/ T) Lf, where (T) = th bulk... [Pg.283]

The concentration of free hydrogen ions in solutions is measured by the pH scale.. Nearly all large biological molecules have theor organization influenced by interactions with water. Describe this interaction as it exists with carbohydrate molecules. [Pg.62]
