Computational fluid dynamics (CFD) combines continuum and discrete theories for fluid modeling with computational algorithms for fluid simulation. It is an important research area since there is a wide range of natural phenomena that can be modeled through fluid theory. Some common engineering examples are pumps, fans, turbines, airplanes, ships, rivers, windmills, pipes, and more recently, the hemodynamics of the arterial system. This book examines several characteristics of CFD, as well as its applications and analysis.
