This long-awaited, physics-first and design-oriented text
describes and explains the underlying flow and heat transfer theory of secondary air systems. An applications-oriented focus
throughout the book provides the reader with robust solution techniques, state-of-the-art three-dimensional computational
fluid dynamics (CFD) methodologies, and examples of compressible flow network modeling. It clearly explains elusive concepts
of windage, non-isentropic generalized vortex, Ekman boundary layer, rotor disk pumping, and centrifugally-driven buoyant
convection associated with gas turbine secondary flow systems featuring rotation. The book employs physics-based, design-oriented
methodology to compute windage and swirl distributions in a complex rotor cavity formed by surfaces with arbitrary rotation,
counter-rotation, and no rotation. This text will be a valuable tool for aircraft engine and industrial gas turbine design
engineers as well as graduate students enrolled in advanced special topics courses.
