System heterogeneity

The discussion of combustion fundamentals so far has focused on homogeneous systems. Heterogeneous combustion is the terminology often used to refer to the combustion of Hquids and soHds. From a technological viewpoint, combustion of Hquid hydrocarbons, mainly in sprays, and coal combustion are of greatest interest. [Pg.520]

The heterogeneous batch conversion system illustrated in Figure 31G is phenomenologically even more complex than the homogeneous batch conversion system. Heterogeneous batch conversion is found in small-scale applications, for example wood stoves. Research activity is also very high in this area [43,44]. The big problems are gaseous pollutants in the emissions and the low efficiency of the stoves. [Pg.106]

The reaction rate is high, in spite of system heterogeneity. [Pg.13]

In the following, we will often be concerned with ternary systems. Heterogeneous binary systems have two phases in equilibrium and are nonvariant (at given P and T). When two ternary phases are in contact, the system still has one (thermodynamic) degree of freedom. A ternary phase has three independent transport coefficients iee., Ln,L22, and /. ). [Pg.68]

Evaporative mass transfer of volatile solvents through microporous hydrophobic membranes is employed in order to concentrate feed solutions above their saturation limit, thus obtaining a supersaturated environment where crystals may nucleate and grow. In addition, the presence of a polymeric membrane increases the probability of nucleation with respect to other locations in the system (heterogeneous nudeation)... [Pg.268]

Developing approach has given an explanation at what conditions the matrices with macroscopic non-uniformities (e.g., lamellar systems, heterogeneous inclusion phases, etc.) and with effective macroscopic diffusion coefficients in the latter case, a matrix is considered as a homogeneous one and when the phenomenological model of double sorption, which operates with sorption sites of two types could be used [190-192]. [Pg.416]

Here, dg is a spatial fractal dimension of the point set where relaxing units are interacting with the surroundings. R is the size of a sample volume section where movement of one relaxing unit occurs. Rq is the cutoff size of the scaling in the space or the size of the cooperative domain. G is a geometrical coefficient of order unity, which depends on the shape of the system heterogeneity. For example, the well-known two-dimensional recurrent fractal Sierpinski carpet has dG = ln(8)/ ln(3) 1.89, G = V3/4 0.43 [213],... [Pg.110]

From an experimental standpoint, the ability to use concentrated suspensions offers obvious advantages when compared to other potentiometric and micro-electrophoretic techniques. Such conditions are more analogous to the solid/solution ratio encountered in a typical soil/sediment environment, but with less kinetic restrictions and system heterogeneity than encountered in the held. In addition, small aliquot suspensions can be removed during analysis for characterization using another technique. The large sample volumes and high colloidal loads, however, may restrict the use of acoustic techniques to idealized laboratory systems where sufficient sample is available. [Pg.293]

This book is the first volume of a Treatise on Thermodynamics based on the methods of Gibbs and De Donder. It deals with the following topics fundamental theorems, homogeneous systems, heterogeneous systems, stability and moderation, equilibrium displacements and equilibrium transformations, solutions, azeotropy, and indifferent states. The second volume deals with surface tension and adsorption while the third and last will be concerned with irreversible phenomena. [Pg.562]

Catalytic performance for any system, heterogeneous or homogeneous, is generally assessed by measuring the activity (rate of reaction) and selectivity of the catalyst for reactions of Interest. A comparison of reaction rates for catalysts prepared using different synthetic methods or different supports is used to Identify the parameters which Influence catalyst activity and selectivity. For studies involving heterogeneous catalysts and Immobilized catalysts, reactant transport to the active sites must occur at a sufficient rate that the observed activity reveals information about the intrinsic properties of the catalytic site. [Pg.69]
