A vivid introduction to fluid simulation.

Topic covered: rarefied gas dynamics, continuum gas dynamics, fluid motion descriptions & coordinates (spatially fixed (Eulerian), material-fixed (Lagrangian), arbitrary), reducibility aspects, motivation on modeling unresolved flow structures, ensemble averages of microscopically and macroscopically varying data, usefulness of the modeling hierarchy, simplifying and decoupling the evolution equations, Navier-Stokes equations, compressible flow and the incompressible flow assumptions, and buoyancy-driven flow (Boussinesq approximation).
