Quiet film

For a triphasic reaction to work, reactants from a solid phase and two immiscible liquid phases must come together. The rates of reactions conducted under triphasic conditions are therefore very sensitive to mass transport effects. Fast mixing reduces the thickness of the thin, slow moving liquid layer at the surface of the solid (known as the quiet film or Nemst layer), so there is little difference in the concentration between the bulk liquid and the catalyst surface. When the intrinsic reaction rate is so high (or diffusion so slow) that the reaction is mass transport limited, the reaction will occur only at the catalyst surface, and the rate of diffusion into the polymeric matrix becomes irrelevant. Figure 5.17 shows schematic representations of the effect of mixing on the substrate concentration. [Pg.126]

For turbulent flow of a fluid past a solid, it has long been known that, in the immediate neighborhood of the surface, there exists a relatively quiet zone of fluid, commonly called the Him. As one approaches the wall from the body of the flowing fluid, the flow tends to become less turbulent and develops into laminar flow immediately adjacent to the wall. The film consists of that portion of the flow which is essentially in laminar motion (the laminar sublayer) and through which heat is transferred by molecular conduction. The resistance of the laminar layer to heat flow will vaiy according to its thickness and can range from 95 percent of the total resistance for some fluids to about I percent for other fluids (liquid metals). The turbulent core and the buffer layer between the laminar sublayer and turbulent core each offer a resistance to beat transfer which is a function of the turbulence and the thermal properties of the flowing fluid. The relative temperature difference across each of the layers is dependent upon their resistance to heat flow. [Pg.558]

The situation resembles that of a horde of Hollywood hopefuls lined up for a limited number of slots as extras in a film. Only so many eager faces react with an available slot to produce a happily (albeit pitifully) employed actor. The remaining actors are in excess, muttering quietly all the way back to their jobs as waiters. In this scenario, the slots are the limiting rec ent. [Pg.135]

A liquid does not necessarily begin boiling when the temperature reaches the boiling point. If kept perfectly quiet, and especially if covered with a film of oil, water may be raised several degrees above its normal boiling point, before it suddenly boils with explosive violence it then returns to its line boiling point. [Pg.249]

At the outset of any treatment it is essential for good results to establish the best combination of these variables in relation to the products concerned the most important single factor is the flame, and the ratio of air to gas must be adjusted to give a quiet blue flame with a well-defined pale blue cone. Just as with the electrical treatment of film, over- or under-treatment can give rise to difficulties—and for this reason too it is necessary to establish the parameters and to keep within them. [Pg.233]

In our world, it is hard to imagine a day without film or media. In the same venue, what would drug discovery be without the natural product I predict that, while it may be quiet on set , drug discovery and its investors are likely to return to natural products as a fundamental resource and the claims that they are ready to shoot will again be heard through the discovery sector. Thus, I conclude it is time to stop worrying about the importance or relevance of natural products within the pharmaceutical sector and get out and film. [Pg.69]

Nevertheless by 1910 the first film studio opened its doors inside a tavern on Sunset Boulevard, within seven short years the quiet community started by the Wilcoxes had vanished. [Pg.505]

I finally turned around and said, Quiet They nodded, as though I was describing an attribute of the theater. I might as well have said Dark or Chairs in rows They embarked anew on another discussion of whether or not that actor was in that Jack Nicholson film. [Pg.606]

As operating speeds get higher the metal to metal contact of rollers and track add considerably to the plant noise level. Since quietness is recognized as a desired and mandatory condition of the workplace, the silent operation of the fluid film system is another of its many important advantages. [Pg.563]

The fluid film processor can match any size, speed, formulation capability, temperature, pressure, energy use, control, and duty capability of a double belt conveyor for the production of cellular panel produced of urethane, cyanurate or phenolic and two flexible skins. It will easily fit into the same space and as a replacement may then offer the capability of higher speeds, higher densities, greater accuracy, smoother surface and greater core material versatility. In addition, its quietness safety and reduced maintenance make the replacement a welcome change. [Pg.564]

Extrusion by pol3Tner hose blowing may produce both single-layer and multilayered inhibited films. It is highly productive, quiet simple and facilitates regulation of dimensions, structure, physical-mechanical and other characteristics of the film materials within a wide range. [Pg.99]
