Fluid dynamics and heat transfer

In the case of convective dryers, the drying mediurrt, i.e., warm air, flows either past or in the case of a solid bed through the drying good. The air velocity is chosen according to the reqrrirements concerning heat transfer and pressure drop.

Computer modelling provides powerful and convenient tools for the quantitative analysis of fluid dynamics and heat transfer in non-Newtonian polymer flow systems. Therefore these techniques arc routmely used in the modern polymer industry to design and develop better and more efficient process equipment and operations. The main steps in the development of a computer model for a physical process, such as the flow and deformation of polymeric materials, can be summarized as ... 

For annuli containing externally Hnned tubes the heat-transfer coefficients are a function of the fin configurations. Knudsen and Katz (Fluid Dynamics and Heat Transfer, McGraw-Hill, New York, 1958) present relationships for transverse finned tubes, spined tubes, and longitudinal finned tubes in annuli.

The subject of the book is fluid dynamics and heat transfer in micro-channels. This problem is important for understanding the complex phenomena associated with single- and two-phase flows in heated micro-channels.

These questions touch on the theoretical fundamentals of models, these being based on dimensional analysis. Although they have been used in the field of fluid dynamics and heat transfer for more than a century - cars, aircraft, vessels and heat exchangers were scaled up according to these principles - these methods have gained only a modest acceptance in chemical engineering. The reasons for this have already been explained in the preface.

For fluid dynamics and heat transfer investigations related to food processing, the necessaiy tja data may be obtained from models developed for i] data using relationships based on the Cox-Merz mle (Rao, 1992 Rao and Cooley, 1992). These results were described in detail elsewhere (Yang, 1997 Yang and Rao, 1998, 1998b, 1998c) and will be reviewed in brief here.

Mass transfer rates in gas-flowing solids-fixed bed contactors are expected to be high, according to fluid dynamics and heat transfer behavior. Somewhat lower values of mass transfer coefficients than those expected were reported in the literature [6,35-37]. The reasons for that are the effects of segregation as well as strong influence of axial backmixing. Apart from this, mass transfer rates depend on size and structure (porosity) of flowing solids [36].

Computational Fluid Dynamics (CFD) and Process Simulation are important tools for the design and optimization of chemical processes (Bezzo et al., 2000). CFD is a particularly powerful tool for the study of fluid dynamics and heat transfer with detailed account of complex equipment geometry. Nonetheless, despite many recent improvements, CFD s ability to describe the physics or solve the underlying numerical problems in several application areas is still limited. Adsorption technology is an application area where the numerical methods employed in most CFD packages are inadequate to solve the strongly coupled nonlinearities introduced by the presence of the adsorbed phase.
