Design and analysis

To set up a factorial design, the experimental domain must be specified. For a two-level design this means assigning a low level, (-), and a high level, (+), to each factor. In this case the following levels were chosen  

Three variables will give eight different combinations of the variable settings. These experiments were run and are summarized in the classic representation of a factorial design shown in Table 5.2. 

The bottom line of Table 5.2 contains the experiment labels. These should be interpreted as follows 1 is the experiment in which all factors are at the low level a is the experiment in which all factors, except A, are at the low level ab is the experiment in which all factors except A and B are at the low level etc. The experiments given in Table 5.2 are more easily surveyed if they are presented as the sign table shown in Table 5.3

The most frequent application of phase-equilibrium calculations in chemical process design and analysis is probably in treatment of equilibrium separations. In these operations, often called flash processes, a feed stream (or several feed streams) enters a separation stage where it is split into two streams of different composition that are in equilibrium with each other.

There are special numerical analysis techniques for solving such differential equations. New issues related to the stabiUty and convergence of a set of differential equations must be addressed. The differential equation models of unsteady-state process dynamics and a number of computer programs model such unsteady-state operations. They are of paramount importance in the design and analysis of process control systems (see Process control). 

When a reaction has many participants, which may be the case even of apparently simple processes like pyrolysis of ethane or synthesis of methanol, a factorial or other experimental design can be made and the data subjected to a re.spon.se. suiface analysis (Davies, Design and Analysis of Industrial Experiments, Oliver Boyd, 1954). A quadratic of this type for the variables X, Xo, and X3 is...

The reader should be exposed to both micromechanics and macromechanics in order to function effectively in either material design or structurai design. The main thrust of this book is in iine with structurai design and analysis requirements. Thus, the point of our addressing micromechanics is to better understand how and why composite materials function.
