These surfaces are generalizations of classical invariant manifolds, known in dynamical systems theory, to finite-time unsteady flow data.

Falling leaves and seeds, fishes, and birds all encounter unsteady flows similar to that seen around an insect.
13.
For unsteady flow, HEC-RAS solves the full, dynamic, 1-D Saint Venant Equation using an implicit, finite difference method.
14.
Conversely, the Keulegan Carpenter number is related to the oscillation frequency of an unsteady flow into which the object is placed.
15.
Lagrangian coherent structures ( LCSs ) are influential material surfaces that create clearly recognizable patterns in passive tracer distributions advected by an unsteady flow.
16.
He and his many students pioneered research in wing theory, unsteady flow, magnetohydrodynamics, and designed a sophisticated wind tunnel design to study transonic flight.
17.
The characteristics of a dielectric barrier discharge ( DBD ) plasma actuator when exposed to an unsteady flow generated by a shock tube is examined.
18.
When there are free vortices outside of the body, as may be the case for a large number of unsteady flows, the flow is rotational.
19.
In the aircraft example, the observer on the ground will observe unsteady flow, and the observers in the aircraft will observe steady flow, with constant streamlines.

Prof . Shyy has made substantial contributions to air and space flight vehicle research and development, fluid machinery design optimization, and computational methods for complex unsteady flows.
