Description Fluid mechanics is the study of how fluids behave and interact under various forces and in various applied situations, whether in liquid
or gas state or both. The author compiles pertinent information that are introduced in the more advanced classes at the senior level
and at the graduate level. ?Advanced Fluid Mechanics? courses typically cover a variety of topics involving fluids in various multiple
states (phases), with both elastic and non-elastic qualities, and flowing in complex ways. This new text will integrate both the simple
stages of fluid mechanics (?Fundamentals?) with those involving more complex parameters, including Inviscid Flow in multi-dimensions,
Viscous Flow and Turbulence, and a succinct introduction to Computational Fluid Dynamics. It will offer exceptional pedagogy, for both
classroom use and self-instruction, including many worked-out examples, end-of-chapter problems, and actual computer programs that can
be used to reinforce theory with real-world applications.
Professional engineers as well as Physicists and Chemists working in the analysis
of fluid behavior in complex systems will find the contents of this book useful.All manufacturing companies involved in any sort of systems
that encompass fluids and fluid flow analysis (e.g., heat exchangers, air conditioning and refrigeration, chemical processes, etc.) or
energy generation (steam boilers, turbines and internal combustion engines, jet propulsion systems, etc.), or fluid systems and fluid
power (e.g., hydraulics, piping systems, and so on)will reap the benefits of this text.
