Abstract : This grant enabled acquisition of new experimental infrastructure necessary for testing novel and fundamental theory/numerics that, ultimately, may lead to revolutionary practical methods for the prediction and control of unsteady and turbulent flows. Recent work suggests a class of exact Navier-Stokes solutions termed \Exact Coherent Structures (ECS) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]may provide new and powerful ways to describe turbulence; as one example, PI Schatz and Co-PiGrigoriev demonstrated experimentally the dynamical role of ECS for 2D turbulence [13].
