Flow modeling project, step

The first step is to define the objectives of the flow model, and to identify those flow aspects that are relevant for the performance of the reactor. Then, the engineer must identify and quantify the various times and space scales involved, as well as the geometry of the system. These actions allow the problem to be represented by a mathematical model. Creating this model accurately is the most crucial task in the flow modeling project. 

Further refinement of the flow models from Step 3 for adaptation into field-scale simulators and development of one-and three-dimensional simulators for eventual field project design. Phenomenological determinations by high-pressure experiments of dispersion properties required of sweep control surfactant systems and selection of homologous series of surfactants (42-45). 

The overall process of any computational flow-modeling project was discussed in Section 1.2 (see Fig. 1.11 for key steps). It will be instructive to re-examine such a process with the background of Chapters 2 to 7. The first step of any flow-modeling project is to identify key controlling processes and relate these controlling processes to underlying fluid dynamics. This analysis will allow one to formulate clear objectives for the flow-modeling exercise. It must be mentioned here that, usually, the potential... 

The objectives of this project are consistent with the objectives (1) and (4) above. The general objective of this project has been to verify a new measurement method to analyse the thermochemical conversion of biofuels in the context of PBC, which is based on the three-step model mentioned above. The sought quantities of the method are the mass flow and stoichiometry of conversion gas, as well as air factors of conversion and combustion system. One of the specific aims of this project is to find a physical explanation why it is more difficult to obtain acceptable emissions from combustion of fuel wood than from for example wood pellets for the same conditions in a given PBC system. This project includes the following stages ... 

The future steps of the project will be to adapt the model to the flow of reacting granular solids and to incorporate this model in a global model with thermal and chemical parts.
