The influence of turbulence was studied somewhat earlier by Bag-otskaya (Bl). Local coefficients of transport of water into an air jet were evaluated experimentally by Spielman and Jakob (S20). These essentially macroscopic studies supplement the investigations reported elsewhere in this discussion and contribute to the background of experimental information concerning material transport in fluid systems.

We reviewed some aspect of passive transport in fluid flows. As far as inert substances are concerned, we described the problem of transport from a Lagrangian point of view focusing on single-particle properties. In particular, the conditions for having asymptotic standard or anomalous diffusion have been discussed in details. As for the problem of reacting substances, we study the... 

Gases are transported liquefied in so-called gas RTCs either under pressure or supercooled. Fluids are transported in fluid RTCs that can be emptied on top or bottom or both. Transported Uquids are typically not under pressure. Depending on the volume, the payload for both types of RTCs varies between approximately 12 and 70 tons. 

Physical modeling of CVD processes means solving the Navier-Stokes equations, partial differential equations for mass and heat transport in fluids given the constant boundary conditions of the reactor. These processes affect the uniformity of the deposit in all parts of the reactor. The proper name for CVD reactor physics is chemical vapor technology (CVT) and it is a subject of some significance for industrial reactor design. (This branch of continuum physics is outside the scope of this book, which is concerned with materials rather than machinery.)... 

Chapter 5 considers the stabiUty of fluid interfaces, a subject pertinent both to the formation of emulsions and aerosols and to thdr destruction by coalescence of drops. The closely related topic of wave motion is also diseussed, along with its implications for mass transfer. In both cases, boundary eonditions applicable at an interface are derived—a significant matter because it is through boundary conditions that interfacial phenomena influence solutions to the governing equations of flow and transport in fluid systems. 

Other adaptations of the deformation potential theory to the problem of electron transport in fluid argon were reviewed by Steinberger (1987). 

An artifact of this kind of decomposition is that it raises the question of how, and on what scale, individual processes (atoms) (e.g., clouds, radiation, chemistry, etc.) interact, and hence the extent to which parameterizations must be coupled to one another, and not just to larger-scale processes. Thermodynamic analogies are useful to a point for instance, diffusion parameterizes molecular transport in fluids. However, any attempt to develop a kinetic theory capable of aggregating many small-scale processes is impeded by our lack of understanding of what exactly constitutes the atoms and the rules that govern their behavior.
