Computation of Unsteady Separation Using Lagrangian Procedures
The interaction between increased knowledge of unsteady separation processes and computational techniques is examined, emphasizing the use of Lagrangian coordinates. Examples include boundary layer solutions of two dimensional unsteady flows, and separation from rotating and translating spheres. Advances in Lagrangian techniques for the Navier-Stokes equations are illustrated by means of high resolution random-walk computations of the impulsively started circular cylinder.
