Future developments system flow

Future developments that may facilitate ocean measurements from vessels or buoys include miniaturization of chromatographic equipment (so less solvent is needed per analysis), new solvent transport systems, such as electrokinetic transport, to reduce power requirements on the pumps, and more sensitive detectors for liquid chromatography. Certain combinations of very short columns and flow injection analysis are also promising for real-time studies. 

The civilization biorefinery will be a network of integrated systems. All solutions will be site-specific, the actual situation and future developments have been taken into consideration and have to be described. Based on improved material flow steering, advanced technologies and networking scenarios for situation improvements have to be developed and evaluated with respect to the specific situation. Following major steps are necessary... 

Redox flow battery systems are promising devices, because the tendency is toward the development of low-cost systems, and future developments seem to be leaning toward choosing less toxic redox couples, more abundant materials, more stable membranes and effective recycling processes. Electrolytes can always be reused provided there is no precipitation of oxides - a phenomenon which occurs at low temperature. 

The future development of improving the heat flow in cooking systems must go in the direction of a still better adaption to the variable forms of cookware (base form, pot size, and material). An automatic adaptation of the local conditions for heat flow to poor-quality cookware is a possibility. If these developments are successfully implemented, raising the specific power of the heating elements could be the next step. Furthermore, an automatic adaptation between the shape of the zone to be heated and the different cookware sizes is imaginable.

There are also many other fuel cell technologies that are not yet mainstream but may become mainstream in the future. Metal-air battery systems are really a hybrid between a battery with stored fuel and a fuel cell with flowing oxidizer. Biological fuel cells represent laboratory-based nascent technologies with very low power density. However, the potential advantages of these systems for power neutral waste remediation is worthy of future development. 

To conclude, a brief review on the state-of-art of the rheology of structured fluids has been carried out giving special emphasis on the structure-rheology correlation. Two systems have been investigated polymeric liquids and dispersions. After a brief introduction on fluid mechanics, material functions and standard flows are explained. Then, existing theories are summarized and compared with experimental results. Even thongh current researchers continue searching for new constitutive equations, those reported in this chapter serve as a base for future developments. 

Particle trajectories can be calculated by utilizing the modern CFD (computational fluid dynamics) methods. In these calculations, the flow field is determined with numerical means, and particle motion is modeled by combining a deterministic component with a stochastic component caused by the air turbulence. This technique is probably an effective means for solving particle collection in complicated cleaning systems. Computers and computational techniques are being developed at a fast pace, and one can expect that practical computer programs for solving particle collection in electrostatic precipitators will become available in the future. 

From this discussion of parameter evaluation, it can be seen that more research must be done on the prediction of the flow patterns in liquid-liquid systems and on the development of methods for calculating the resulting holdups, pressure drop, interfacial area, and drop size. Future heat-transfer studies must be based on an understanding of the fluid mechanics so that more accurate correlations can be formulated for evaluating the interfacial and wall heat-transfer coefficients and the Peclet numbers. Equations (30) should provide a basis for analyzing the heat-transfer processes in Regime IV.
