particularly focusing on the critical effect of the fluid viscosity. The evolutionary development of the lift problem of a flat-plate airfoil is reviewed as a canonical case from the classical inviscid circulation theory to the viscous-flow model. In particular...
Within the low Reynolds number regime at which birds and small air vehicles operate (Re=15,000-500,000), flow is beset with laminar separation bubbles and bubble burst which can lead to loss of lift and early onset of stall. Recent video footage of an eagle's wings in flight reveals an...
The most influential and elegant example is the triple-deck theory [15–17], which clarifies quantitatively the formation of free shear layer from separation of boundary layer at smooth surface, corner, or trailing edge of the wall, that is the very physics behind the transition from simple ...

The alula is a high-lift device located at the leading edge of bird wings that allows these animals to fly at large angles of attack and low speeds without wing stalling. The influence of the alula in the wing aerodynamics seems to be similar to that of leading-edge slats in aircraft win...
Changes in the formation, development, and bursting of the separation bubble may produce a pronounced impact upon the pressure plateau and hence the aerodynamic performance of a wing (Toppings and Yarusevych, 2023, Li et al., 2022, Mitra and Ramesh, 2019). The separation bubble is sensitive ...

The concept of a critical state is discussed and it is shown that crossing a critical state produces large transients in the dynamic airloads. Next, several aircraft configurations are examined to show the importance of unsteady aerodynamics on the flight dynamics of aircraft maneuvering at large ...
