Material and Spatial Description of the Flow Field
Engineering fluid dynamic design process has been experiencing a continuous progress using the Computational Fluid Dynamics (CFD) tools. The use of CFD-tools opens a new perspective in simulating the complex three-dimensional (3-D) engineering flow fields. Understanding the details of the flow motion and the interpretation of the numerical results require a thorough comprehension of fluid mechanics laws and the kinematics of fluid motion. Kinematics is treated in many fluid mechanics texts. Aris  and Spurk  give an excellent account of the subject. In the following sections, a compact and illustrative treatment is given to cover the needs of engineers.
