Separating and reattaching flows are important in a large number of engineering configurations. The flow through a sudden expansion (backward-facing step) represents a conceptually simple case of this class of flows and hence ...

Atmospheric and oceanic flows are often modeled as two-dimensional due to their large planar extents (∼ 1000 km) and small vertical extent (∼ 10 km). Most phenomena in these systems are governed by the theory of two-dimensional ...
