Introduction

Fluid mechanics is one of the most important subjects of human interest. To be more specific, it encompasses aerodynamics, hydrodynamics, magneto hydrodynamics, vortex dynamics, gas dynamics, computational fluid dynamics (CFD), convection heat transfer, flows of turbo machinery, acoustics, biofluids, oceanography, meteorology, glaciology, geomagnetism, continental drift, mantel convection, atmospheric dynamics, wind engineering, filtering, mixing, planetary atmospheres, planetary cores, comet tails, cryogenics, river flooding and meandering and the dynamics of multi-phase flows. It is now well-known that modern design of aircraft, spacecraft, automobiles, ships, land and marine structures, power and propulsion systems etc is not possible without knowledge of relevant fluid mechanics.
