Fluid kinetics

According to some recent results (Sect. 5.5), the dependence of K on e and qs is more involved than suggested by Eq. (94). The dependence of K on ris is much weaker than a direct proportionality and the correct flow parameter to be used in Eq. (94) should be the local fluid kinetic energy ( v2) rather than the strain rate (e). For a constant flow geometry, however, the two variables v and e are interchangeable. At the present stage and in order not to complicate unduly the kinetic scheme, it will be assumed that the rate constant K varies with the MW and strain rate as ... 

Flynn and Dickens [142] have translated the relaxation methods of fluid kinetics into terms applicable to solid phase thermogravimetry. The rate-determining variables such as temperature, pressure, gas flow rate, gas composition, radiant energy, electrical and magnetic fields are incremented in discrete steps or oscillated between extreme values and the effect on reaction rate determined. 

With the exception of the discussion of fluid kinetic energies, for which well-developed design equations are available, the work in this section has served primarily to draw attention to the lack of information in this area.

A criterion for the prediction of minimum stirrer rotation speeds for the suspension of coarse-grain particles (Archimedes number > 40) is derived by Molerus and Latzel (1987). They showed that the minimum stirrer rotation speeds can be predicted by the evaluation of two diagrams the drag of fluidized particles as a function of concentration, and the pressure-head volumetric flow-rate characteristics of the agitated vessel. The latter can be obtained using the similarity of fluid-kinetic machines and can be expressed as lAav = /([Pg.48]

Centrifugal pumps work by giving the fluid kinetic energy and then converting this to injection work. They are generally high-flow-rate, low-pressure-rise devices. 

Steady-state analysis implies that the combination of fluid kinetic energy per unit volume and dynamic pressure is not time dependent. The potential flow equation of motion suggests that this combination of fluid kinetic energy per unit volume and dynamic pressure is not a function of any independent spatial variable. Consequently,... 

The major uses of lndlum-111 in medicine are listed in Table 2. Indium-111 labeled DTPA is the preferred agent for the study of cerebral spinal fluid kinetics (cisternography)( ). Indium-labeled bleomycin has been used for tumor scanning C2.), although citrate has achieved greater clinical use. It appears that indium bleomycin is in fact a weak chelate and the in vivo distribution is very similar to that of indium transferrin.
