The essential fact to remember at this stage is that within the world of continua, as currently applied to describe the macroscopic behavior of fluids, there is always an unavoidable level of empiricism in the models. It is therefore important that you take notice already that any modeling assumption will be associated with a generally undefined level of error when compared to the real world. Therefore, keep in mind that a good understanding of the physical properties and limitations of the accepted models is very important, as it is not unusual to discover that discrepancies between CFD predictions and experiments are not due to errors in experimental or numerical data, but are due to the fact that the theoretical model assumed in the computations might not be an adequate description of the real physics.

2. What is going to happen? Will the drop stay in its position? As you probably know from basics physics, we observe that after a certain time the whole of the reservoir will become colored. What has happened? 2 A colored dye diffusing in a water reservoir. tex 27/4/2007 15: 37 Page 35 The Basic Equations of Fluid Dynamics 35 Due to the molecular agitation, the dye molecules are constantly in collision with the water molecules and will be ‘hit’many times in all directions to wind up in arbitrary positions.

The following topics will be dealt with: • The concepts of consistency, stability and convergence of a numerical scheme and a method for the analysis of stability in Chapter 7, including the quantitative evaluation of the errors associated to a selected scheme. • A general approach to properties of numerical schemes will be presented in Chapter 8, together with a methodology to generate schemes with prescribed accuracy. In addition this chapter will introduce the property of monotonicity leading to nonlinear high-resolution scheme.
