It is assumed in the above-mentioned methods that the influence of confined space on the supplied jet can be described by the reduction of the axial component and the value as for jet development in the counterflow. The value of i/,. is assumed to be the same throughout each cross-section but variable along the jet length. The value of can be found from the continuity equation, which in the case of jet distribution in a space of cylindrical shape can be presented as... [Pg.487]

The first demonstration, to our knowledge, that the properties of a gas or liquid within a mesoporous cavity change was made by Dosseh et al. studying the properties of cyclohexane and benzene confined in MCM-41 and SBA-15. The effect was related to the influence of the inner surfaces of mesoporous silica. Other authors have further demonstrated the influence of confinement on the adsorption and properties of fluids within an ordered mesoporous material. Flowever, Fajula et were the... [Pg.89]

Investigation of the influence of confinement on the total end effect, has shown that in the range of diameters between ca 1.5 and 2 inches, the maximum effective confinement obtainable with steel was reached with a tube ca 0.5 inches thick. Also, it was found that with maximum confinement the effective charge length Lm in this range of diameters increased only ca one charge diameter above that of unconfined charges, while the total end effect about doubled... [Pg.264]

Accdg to Baum et al (Ref 10), the walls of confining container restrict the penetration of side waves of rarefaction into zone of transformation and this helps to utilize more fully the energy of chemical reaction in the deton wave. This leads to increase in deton vel and the influence of confinement is greater for expls of low velocity (such as AN expls) than forbrisant expls like RDX, PETN, etc. [Pg.658]

The influence is the lowest for initiating expls, such as MF or LA. For brisant expls the influence of confinement is noticeable only at small diams and low densities of charges... [Pg.658]

In order to have a better understanding of the influence of confinement upon radiolysis, we need to have a global view of the confinement-induced modifications of water properties and of the perturbation of diffusion processes inside pores. [Pg.328]

The influence of confining boundaries on the effective diffusivity as reflected by Eqs. 15a,b has been repeatedly applied to determine the pore surface in rocks or beds of sand grains [106-115]. In [116], this concept has been for the first time successfully applied to beds of zeolites. Figure 9 shows the results of these studies, which have been performed with two different samples of Na-X, one loaded with n-hexane (two molecules per supercage), the other with n-hexane and hexafluoromethane (one molecule per supercage for either). In both samples, for the n-hexane measurements a temperature of 298 K was chosen, where the n-hexane molecules were found to be totally confined so that the data analysis could be based on Eq. 15a. The measure-... [Pg.104]

By measuring the surface forces one can therefore obtain important information not only on the structure of a liquid crystal, but also on the influence of confining surfaces on orientational and positional ordering on a molecular level. This Chapter describes experimental techniques that are used for the measurements of surface forces and is focused on the results of the experiments that have been recently performed in the isotropic, nematic and smectic-A phases. [Pg.28]

Geerts et al. have undertaken a study of the alignment of phthalocyanine 19 columns in thick (a few micrometer) and thin (a few tens of nanometers) films and on the influence of confinement on the occurrence of homeotropic alignment [113]. The orientation of the columns in those films is characterized by polarized optical microscopy and atomic force microscopy as a function of the preparation method, the polarity and roughness of the substrate and the number of DLC-solid interfaces, i.e. one or two. The control of columnar alignment is determined by the... [Pg.221]
