Pipe Coil Pipe coil for submersion in coil-box of water or sprayed with water Is simplest type of exchanger. Condensing, or relatively low heat loads on sensible transfer. Transfer coefficient is low, requires relatively large space if heat load is high. 0.5-0.7... [Pg.25]

Open Tube Sections (Water cooled) Tubes require no shell, only end headers, usually long, water sprays over surface, sheds scales on outside tubes by expansion and contraction. Can also be used in water box. Condensing, relatively low heat loads on sensible transfer. Transfer coefficient is low, takes up less space than pipe coil. 0.8-1.1... [Pg.25]

Open Tube Sections (Air Cooled) Plain or finned tubes No shell required, only end heaters similar to water units. Condensing, high level heat transfer. Transfer coefficient is low, if natural convection circulation, but is improved with forced air flow across tubes. 0.8-1.8... [Pg.25]

Quantum chemistry aims to understand a large variety of chemical facts. In some systems an interesting feature was obtained whose study and whose application can help to reduce the computational effort considerably this is the transferability. Transfer-ability can be interpreted in several ways. The orbitals, on the one hand, may be considered transferable in the case when certain properties of these orbitals are close to each other to a certain extent (Rothenberg, 1971). The transferability of orbitals can be discussed directly on the other hand too. Orbitals of small molecules can be used for constructing the wave-function of related, larger molecules. This can be done with or without further optimizations. In this interpretation the orbitals are transferable if the molecular properties calculated with and without optimizations are close to each other (O Leary et al, 1975). The transferability of orbitals for cyclic hydrocarbons was discussed exhaustively (Edmiston et al., 1963). [Pg.41]

Chapter 8 Inteifacial Mass Transfer. Transfer of mass between two phases - such as air-water, water-solid, and air-solid - is considered in this chapter. The emphasis is on the development of theories to describe the concentration boundary layer for various applications. [Pg.14]

Variations on the vertical dipping technique have been utilized to construct films containing divalent metal ions. For example, the quartz crystal microbalance (QCM) has been used to evaluate the horizontal lifting method of CdSt LB Film construction (26). In this method, the QCM quartz plate was touched to monolayers compressed on a subphase and lifted horizontally. Y-type transfer (transfer ratio of 1) was demonstrated with two centrosymmetric monolayers deposited for each cycle. A combination of the vertical and horizontal dipping techniques has been utilized to prepare multilayer films from an amphiphilic porphyrin compound (27). [Pg.240]

Reversible Energy Transfer. It is almost always assumed that the transfer of triplet energy from the sensitizer to substrate is irreversible. Back transfer, transfer of triplet energy from the acceptor back to the sensitizer, can, however, take place under the right set of circumstances. The following scheme illustrates the mechanism for back transfer. [Pg.259]

External transfer transfer of the absorbate from bulk fluid to outer surface of particle by molecular and convective diffusion. [Pg.17]

Internal transfer transfer of adsorbate from particle surface to interior site by diffusion in the void space of the pores, by surface migration on the pore surface, or by volume diffusion, for example, in the holes in the chemical structure of the solid phase. [Pg.18]

Internal transfer transfer of energy to the outer surface of the solid particle. This is commonly treated as though the particle was homogeneous with a single effective thermal conductivity. [Pg.18]

External transfer transfer of energy from the surface of the particle into the fluid stream. The properties of flowing fluids are such that the resistance to heat transfer can be larger than that for mass transfer, so that a negligible concentration difference may exist between bulk fluid and particle surface and yet the corresponding temperature difference will be significant. [Pg.18]

Coherent population transfer Transfer of population from one quantum mechanical level to another using coherent radiation. The radiation may be provided by either continuous or pulsed lasers. Using the method of adiabatic passage (see STIRAP), 100% population transfer has been achieved. [Pg.145]

Latent heat transfer Transfer of heat required to bring about a phase change (e.g., condensation or vaporization) in a fluid. (Compare to sensible heat transfer.) Many heat exchangers involve both latent and sensible heat transfer. [Pg.305]
