The application of Fluid Mechanics in design relies on the use of empirical results built up from an extensive body of experimental research. In many areas empirical data are supplied in the form of tables and charts that the designer may apply directly. Therefore, in the organization of experimental work and the presentation of its results that dimensional analysis plays important role. Dimensional analysis together with similarity and model testing techniques allow the design engineer to predict accurately and economically the performance of the prototype system. The ability to seek numerical solutions of governing equations under a given set of boundary and initial conditions has led to the development of computational fluid dynamics (CFD), a new discipline in fluid dynamics that had to await the availability of computing power. Along with the traditional approaches of experimental and analytical fluid science, CFD is now widely used within a wide range of engineering applications.
