Fluid dynamics stands central to many branches of science and engineering and touches many aspects of our daily life. Fluid dynamics plays an important role in defence, transportation, manufacturing, environment, energy, industry, medicine and biology. The movement of physiological fluids in the human body, the prediction of the aerodynamic behaviour of moving vehicles, the weather prediction, cooling of electronic components and performance of micro - fluidic devices are all demanding applications of the principles of fluid dynamics. Owing to the complexity of the subject and a wide variety of its applications, fluid dynamics is proven to be a highly exciting and challenging subject of modern sciences. The quest for deeper understanding of the subject has not only inspired the development of the subject itself, but also paved the way for emerging of new techniques and fields such as advanced mathematical methods, numerical methods, experimental techniques and computational fluid dynamics etc.
