Engineering contexts

The full technical details of these processes are beyond the scope of this book (see Further reading for further enlightenment), but it is worth having a slightly closer look at them to get a feel for the engineering context in which each is used. 

The engineering context of the need for multiscale representation of process trends can be best seen within the framework of the hierarchical...

In the strict chemical sense, the term drying refers to removal of water present in solid or fluid materials by treatment with water-reactive chemicals. In a wider (chemical engineering) context, it also refers to use of physical methods to remove any unwanted liquids (or vapours) from solid, liquid or gaseous phases. 

Most chemical reaction engineering textbooks contain material on residence time distribution theory. Levenspiel [17] and Hill [18] present particularly useful introductions as do refs. 9 and 16. The proceedings of a recent summer school [19] contains a brief overview of the field [8] as well as papers describing many specific applications of RTD theory in chemical engineering contexts. Nauman s comprehensive invited review cited earlier [4] is an extremely thorough and yet highly readable contribution to the literature. The book by Nauman and Buffham [20], will no doubt fill a most important gap in the literature on mixing in continuous flow systems. 

The purpose of tracer experiments is to extract information about the system in a chemical reaction engineering context, it is the mixing within the system which is of interest, as represented by the system residence time distribution. Because flow mixing is an inherently linear process, the exact form of the RTD which is recovered from a tracer response experiment should be independent both of the amount of tracer used in the test and also of the particular functional form in which the tracer was... 

Regardless of the reasons behind the conformity, the ramifications for an engineering context are important. Ethical dilemmas arise for engineers almost... 

In general terms, transfer functions arising within a chemical engineering context can almost always be written as a ratio of two polynomials in s. Thus, referring to Fig. 7.10a ... 

Computer system documentation means records that relate to system operation and maintenance, from high-level design documents to end-user manuals. Sidebar 11-1 illustrates some typical SLC documentation. In the software-engineering context, computer systems documentation is regarded as software. All regulatory provisions applicable to software are also applicable to its documentation. 

But, I m getting ahead of the story. First, I ll examine the historical evolution of the subject of fluid mechanics and transport phenomena in a chemical engineering context. Then I will turn to a personal view of a likely future and, in so doing, return to some of the topics that have been mentioned above. 

Cyclic Steady State (CSS) is a unique feature of periodic adsorption processes. It is defuied as a condition whereby the state at the end of each cycle is identical to that at its beginning. Within an engineering context, the theoretical determination of CSS for a given set of periodic conditirms is a key step towards the optimisation of adsorption processes. CSS determination computer simulation, however, is still one of the most challenging procedures for a process engineer to implement. Once achieved, the engineer is more readily able to maximise profit and minimise costs of the adsorption process. 

Within this section, we review the Principles of Sustainable Engineering that were developed at the SanDestin conference, and provide a brief discussion of each of the principles. First, the principles are stated in their entirety. Then, an elaboration is provided to put these principles into an appropriate engineering context. 

The Virtual Design Team (VDT) is an actor-oriented model for the simulation of product development projects that was created at Stanford University. Early versions of VDT were already able to model actors and activities as well as the information flow between them [599, 604]. In subsequent versions, the different goals of actors, the construction of exceptions, and exception handling [771, 812, 813] were accounted for. A process engineering context was not considered in this model. The methodology does not support the participative creation of simulation models. 

In the general rock engineering context, the mapping function could be a classification index value, such as RMR or Q, In the THMC modelling context, we should like the modelling to occur within one overall rock domain in which all the rock properties were statistically homogeneous. However, because of the different natures of the T, H, M and C components, they are not likely to have the same domains, as illustrated by the example content of Table 2. 

The ultimate goal of human performance engineering is the enhancement of performance and safety of humans in the execution of tasks. The more formalized conception of this held was fueled initially by military needs. It has steadily evolved to become an important component in industrial and other settings as well. In a biomedical engineering context, the scope of dehnition applied to the term human not only encompasses individuals with capabilities that differ from those of a typical healthy individual in many possible different ways (e.g., individuals who are disabled, injured, unusually endowed, etc.), but also includes those who are simply healthy (e.g., healthcare professionals). Consequently, one Ends a wide range of problems in which human performance engineering and associated methods are employed. Just a few examples include ...

In a production engineering context, ultraprecision machining is usually referred to a mechanical machining process which is applied to macroscopic workpieces and whose accuracy has been driven to its ultimate technological limits.
