Computer simulation of the reactor kinetic hydrodynamic and transport characteristics reduces dependence on phenomenological representations and idealized models and provides visual representations of reactor performance. Modem quantitative representations of laminar and turbulent flows are combined with finite difference algorithms and other advanced mathematical methods to solve coupled nonlinear differential equations. The speed and reduced cost of computation, and the increased cost of laboratory experimentation, make the former increasingly usehil. 

Sufficient data on process distributions and costs must be collated to characterize manufacturing processes for advanced tolerance models. 

Research looking into tolerance allocation in assembly stacks is by no means new. A current theme is towards an optimization approach using complex routines and/ or cost models (Lin et al., 1997 Jeang, 1995). Advanced methods are also available, such as Monte Carlo Simulation and Method of Moment. ) (Chase and Parkinson, 1991 Wu et al., 1988). The approach presented here is based on empirical process capability measures using simple tolerance models, cost analogies and optimization...

Another detailed method of determining pressures is computational fluid dynamics (CFD), which uses a numerical solution of simplified equations of motion over a dense grid of points around the building. Murakami et al. and Zhoy and Stathopoulos found less agreement with computational fluid dynamics methods using the k-e turbulence model typically used in current commercial codes. More advanced turbulence models such as large eddy simulation were more successful but much more costly. ... 

When the users are not the developers, a major mismatch can result between the material design and the end use. Thus, the developer will have extensive product application development to do, which is both expensive and time-consuming. Initial market potentials can be small, and manufacturing capital costs can be high. Thus, the development of new performance materials as the foundation of a materials business does not look very attractive to materials suppliers. Yet, these enabling technologies are very important to the future development of many basic industries. Some models for the successful development of advanced-performance materials are the following ...
