Computer models to predict the transport processes in concrete
In this chapter, the basic methods used to develop computer models are explained by considering an example. It is shown that the models use the simple equations given in Chapter 1 rather than their integrated forms. A model for pressure-driven flow and diffusion through a waste containment barrier is considered. The lines of code correspond exactly to the equations that are being applied and the key equations and their corresponding code are discussed. Example calculations from the model are presented which show the key influence of adsorption on transport.
