Performance measurement techniques current research

In conjunction with its research activities, TPRC screens the world s literature and collects published information on a wide range of materials in the field of thermophysics. This information concerns data, theoretical estimation methods, and experimental measurement techniques. Technical papers come from journals, abstracting services, reports, doctoral dissertations, masters theses, and many other sources. The full evaluation and analysis of the collected raw data are needed before publications on recommended values can be prepared. Such effort is obviously time consuming and expensive and therefore this critical evaluation is currently performed at a rather modest funding level. The end result is that much of the available world literature is not being processed and distilled. 

In this chapter, we examine current methods for measuring those properties of the catalyst relating to plant performance. These are classified as bulk, particle, and surface properties, including such factors as composition. structure, mechanical properties, surface area, dispersion, and acid-ity (isu Although these measurements also enter into research, specialized techniques in scientific studies are not included, nor do we treat methods that investigate adsorbates, unless they are part of adsorbent characterization. 

Section 14.2 presents a description of the TDL technique for temperature measurement, including the theory and basic principles behind the method. Section 14.3 provides a historical overview of the development of this technique to provide a sense of the considerable amount of research that has been performed in this field to date. Section 14.4 provides details of four TDL-based systems capable of temperature measurement in full-scale environments that are thought to be of particular interest to the industrial combustion community. Finally, Section 14.5 contains some concluding remarks about the current state of TDL sensors and possible outcomes of future developments.
