In physics and engineering, fuid dynamics is a subdiscipline of fuid mechanics that describes the fow of fuids, liquids, and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraf, determining the mass fow rate of petroleum through pipelines, predicting weather paterns, understanding nebulae in interstellar space and modeling fssion weapon detonation. In this book, we provide readers with the fundamentals of fuid fow problems. Specifcally, Newtonian, non-Newtonian and nanofuids are discussed. Several methods exist to investigate such fow problems. Tis book introduces the applications of new, exact, numerical and semianalytical methods for such problems. Te book also discusses diferent models for the simulation of fuid fow.
