This volume as the title indicates is directed entirely at those whose main interest is in the [COLOR=blue! important][COLOR=blue! important]fluid [COLOR=blue! important]mechanics[/color][/color][/color] area. Here however a very wide application field is covered ranging from incompressible slow viscous flow to [COLOR=blue! important][COLOR=blue! important]high-speed[/color][/color] supersonic flows. Such specialised applications as shallow water flow, ocean waves and metal or plastic forming are also included in this text as specific examples.
